Poker Vibrator (Product Code: SLE/CE/38) is an internal (immersion) vibrator used to compact concrete specimens from the inside in concrete testing, civil engineering and site laboratories. It is a practical alternative to a traditional tamping bar, especially when large numbers of specimens must be compacted, and it is offered in four versions that differ in flexible shaft length and tip diameter. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is a Poker Vibrator Used For?

A poker vibrator compacts concrete by vibrating it from within. The vibrating tip at the end of the flexible shaft is lowered vertically into the concrete in the mould; the vibration makes the mix behave like a fluid, so entrapped air rises and escapes and the particles settle into a dense mass. Compaction is usually judged complete when large bubbles stop appearing and the surface takes on a smooth, glossy look.

Withdraw the tip slowly so the hole it leaves closes behind it, keep it clear of the mould walls and base, and avoid over-vibrating, which can cause segregation. Matching the tip diameter to the size of the moulds and the shaft length to your working position is the main selection decision. For a busy casting bay, it is an efficient addition to engineering lab equipment used for cubes, beams and cylinders.

What to Specify When Ordering

• Which of the four available versions you need, by flexible shaft length and tip diameter.
• The types and sizes of moulds you compact, so a suitable tip diameter can be proposed.
• How many specimens you cast per day, which shows whether one or more vibrators are needed.
• Any moulds or hand-compaction tools you want quoted on the same enquiry.

Frequently Asked Questions

What is a Poker Vibrator used for in a concrete lab?
The Poker Vibrator is used for the internal compaction of concrete specimens. Its vibrating tip is immersed in the fresh concrete inside the mould, driving out entrapped air so that cubes, cylinders or beams are dense and give reliable strength results.

How many versions of the Poker Vibrator are available?
The Poker Vibrator (SLE/CE/38) is available as four products, which differ in flexible shaft length and tip diameter. Tell us the moulds you use and we will confirm the details of each option through the contact page.

Is a poker vibrator better than a tamping bar?
A Poker Vibrator is a good alternative to the traditional tamping bar, particularly when large numbers of specimens need compacting, because it consolidates concrete faster and with less manual effort. For occasional small batches or teaching demonstrations, hand tamping can still be adequate.

How do I avoid over-vibrating concrete?
When using a Poker Vibrator, stop once large air bubbles no longer rise and the surface looks smooth and glossy, then withdraw the tip slowly. Vibrating far beyond this point can drive coarse aggregate down and bring excess paste and water to the top, causing segregation.

Who supplies the Poker Vibrator?
The Poker Vibrator is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, based in Ambala, Haryana, India. The company sources it for colleges, testing laboratories, dealers and importers and can combine it with other concrete test equipment on a single quotation.

What should I include when requesting a quotation?

Sand Absorption Cone And Tamper (Product Code: SLE/CE/39) is a conical metal mould with a matching tamper, used to judge when fine aggregate reaches the saturated surface-dry condition for specific gravity and water absorption tests in civil engineering laboratories. The cone is 1.5 inch in diameter at the top, 3.5 inch at the base and 2 7/8 inch high, and the metal tamper weighs 12 ounces. Jain Scientific Equipments Pvt Ltd (ScienceLab) makes the set as an OEM manufacturer at its own factory in Ambala, India.

Specifications

What Is the Sand Absorption Cone Used For?

Specific gravity and absorption results for sand depend on testing it in the saturated surface-dry (SSD) state, when the particle pores are full of water but the surfaces carry no free film. To find that point, a soaked sample is spread out and dried gradually with gentle warm air while being stirred. At intervals, the cone is set large end down on a smooth, non-absorbent surface, filled loosely with sand, lightly tamped with the flat-faced tamper and lifted straight up.

If the moulded sand keeps the shape of the cone, surface moisture is still holding it together; when it slumps slightly on removal, the sample has reached SSD and can be weighed for the next step of the test. Use the tamping and drop procedure given in your laboratory's test standard, and keep the cone clean and dry between trials. It is a small but important item of lab equipment for technical institutes teaching aggregate testing.

OEM Manufacturer

This cone and tamper set is an OEM product of Jain Scientific Equipments Private Limited, which trades as ScienceLab and manufactures it at its own licensed factory at Saha, Ambala, Haryana. The company is a registered MSME enterprise (Udyam UDYAM-HR-01-0003714) whose major activity is manufacturing, and it ships export orders under Importer-Exporter Code AAECJ8618A (DGFT), supplying colleges, laboratories, dealers and importers factory-direct.

Frequently Asked Questions

What is the Sand Absorption Cone And Tamper used for?
The Sand Absorption Cone And Tamper is used to identify the saturated surface-dry condition of fine aggregate. Sand is moulded in the cone and tamped, and its behaviour when the cone is lifted shows whether free surface moisture remains before specific gravity and absorption are measured.

What are the cone dimensions?
The conical metal mould of the Sand Absorption Cone And Tamper (SLE/CE/39) measures 1.5 inch in diameter at the top, 3.5 inch in diameter at the base and 2 7/8 inch in height. Check these dimensions against the test standard your laboratory follows before ordering.

What are the tamper specifications?
The tamper supplied with the Sand Absorption Cone And Tamper is a metal tamping rod weighing 12 ounces. It has a flat, circular tamping face 1 inch in diameter, which lets it compact the sand lightly and evenly without driving it hard into the cone.

How do I know the sand has reached SSD?
Using the Sand Absorption Cone And Tamper, fill and tamp the cone, then lift it vertically. If the sand holds its conical shape, surface water is still present; when it slumps slightly for the first time as it dries, the sample is taken to be at the saturated surface-dry condition.

Who manufactures the Sand Absorption Cone And Tamper?
The Sand Absorption Cone And Tamper is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Laboratories and dealers buy it directly from the manufacturer, which also handles repeat orders.

Can I get an inspection or calibration document?

Concrete Test Hammer Schmidt Hammer N-Type (Product Code: SLE/CE/41) is a rebound-type test hammer used to assess the compressive strength characteristics of hardened concrete non-destructively in structural investigation, site quality-control and civil engineering teaching laboratories. Engineers use it to control the uniformity of concrete and detect weak spots in members, provided the test object is at least 100 mm thick. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is a Schmidt Hammer Used For?

The quality of concrete is judged mainly by its compressive strength, which directly affects the load-bearing capacity and durability of a structure. A rebound hammer gives a quick, non-destructive indication: a spring-driven mass strikes a plunger held against the concrete, and the distance it rebounds reflects the hardness of the surface layer. Because nothing is cut or broken, the same member can be tested at many points and re-tested later.

Typical uses include comparing concrete quality across columns, slabs and walls, locating weak or poorly compacted zones, and deciding where cores should be taken. For meaningful results, test on smooth, clean surfaces, take a set of readings at each location, avoid areas directly over reinforcement, and relate rebound values to crushing tests on the same concrete. It is a core item among test and measurement instruments for structural audits in India and abroad.

Supplier

ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, supplies this N-type Schmidt concrete test hammer to engineering colleges, consultants, structural audit teams, dealers and importers in India and international markets. It is offered alongside other non-destructive and destructive concrete testing equipment, so a complete assessment kit can be sourced through one supplier. The company profile has more information.

Rebound testing is most useful when combined with these methods and tools:

• Ultrasonic Pulse Velocity Tester — checks internal uniformity and defects to complement surface rebound values.
• Concrete cover meter — locates reinforcement so readings can be taken away from bars.
• Concrete Test Hammer — another concrete test hammer listed in the range.
• Automatic digital compression testing machine — crushes cubes or cores to correlate rebound numbers with strength.

See the full Civil Engineering Lab Equipment range.

Frequently Asked Questions

What does the Concrete Test Hammer Schmidt Hammer N-Type measure?
The Concrete Test Hammer Schmidt Hammer N-Type measures the compressive strength characteristics of hardened concrete non-destructively. It is used to control uniform concrete quality and detect weak spots in structures, giving a quick indication without cutting or breaking the member.

What is the minimum thickness of concrete that can be tested?
With the Concrete Test Hammer Schmidt Hammer N-Type, the test object should have a minimum thickness of 100 mm. Thinner or small elements may move or vibrate under the impact, which can distort the reading, so they need a different approach.

Does a rebound hammer replace cube or core testing?
No. The Concrete Test Hammer Schmidt Hammer N-Type gives a non-destructive estimate based on surface hardness. For reliable strength values, rebound readings should be correlated with compression tests on cubes or cores from the same concrete, then used to survey larger areas quickly.

How should readings be taken?
Hold the Concrete Test Hammer Schmidt Hammer N-Type perpendicular to a smooth, clean, dry surface and take several impacts at each test location, spaced apart and clear of edges and reinforcement. Record the orientation of the hammer, because the direction of impact also influences the rebound value.

Ultrasonic Pulse Velocity Tester (Product Code: SLE/CE/42) is a non-destructive testing instrument used to measure the transit time of ultrasonic waves through concrete, so that its uniformity, internal defects and strength can be evaluated in structural testing and civil engineering laboratories. It works with 52 kHz transducers designed to send and receive signals effectively in highly attenuative materials such as concrete, wood, stone and plastic. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is a UPV Tester Used For?

The velocity of an ultrasonic wave in concrete depends on the material's elastic properties and strength. The tester applies a high-voltage pulse to the transmitting transducer, the wave travels through the concrete to the receiving transducer, and the instrument measures the transit time accurately. Dividing the path length by that time gives the pulse velocity: sound, dense concrete returns short transit times, while cracks, voids or weak zones slow the wave down.

Engineers use it to map uniformity across a structure, locate cavities and cracks, assess fire or frost damage and delamination, and track deterioration over time. Couple the transducers to clean, smooth surfaces with a suitable couplant, measure the path length carefully, and compare readings taken the same way. Paired with a rebound hammer, it forms a practical set of test and measurement instruments for condition surveys in India and international markets.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies this Ultrasonic Pulse Velocity Tester from Ambala to universities, structural consultants, testing laboratories, dealers and importers. Buyers building a non-destructive testing kit can source it together with rebound hammers, cover meters and other concrete equipment, and technical questions before purchase can be sent to our team.

• Core Drilling Machine (Motorised) — takes cores to confirm results at suspect locations.

View the complete Civil Engineering Lab Equipment range.

Frequently Asked Questions

What does the Ultrasonic Pulse Velocity Tester measure?
The Ultrasonic Pulse Velocity Tester measures the transit time of an ultrasonic wave passing through concrete between a transmitting and a receiving transducer. From this, pulse velocity is calculated to evaluate uniformity, internal defects and the elastic properties and strength of the material non-destructively.

What transducer frequency does the tester use?
The Ultrasonic Pulse Velocity Tester uses 52 kHz concrete transducers. They are designed to send and receive ultrasonic signals effectively in highly attenuative materials, which makes them suitable for concrete as well as wood, stone and plastic.

Which defects can the UPV tester help detect?
The Ultrasonic Pulse Velocity Tester helps investigate uniformity, cavities, cracks, fire or frost damage, delamination and general deterioration in concrete. Zones where the wave slows down, or where the transit time rises sharply, point to areas that deserve closer inspection or coring.

How does pulse velocity relate to concrete strength?
For the Ultrasonic Pulse Velocity Tester, higher elastic property or strength means a shorter transit time and higher velocity, while weaker or damaged concrete gives a lower velocity. Converting velocity into strength values requires correlation with tests on the same concrete.

Who supplies the Ultrasonic Pulse Velocity Tester?
The Ultrasonic Pulse Velocity Tester is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company supplies it to colleges, laboratories, consultants, dealers and importers, and can quote it alongside other non-destructive testing equipment.

Crack Measuring Microscope (Product Code: SLE/CE/43) is an optical instrument used to measure the width of cracks in concrete members, masonry walls and other structures during condition surveys and civil engineering laboratory work. An adjustable lamp unit lights the crack, a knob brings the image into focus, and the eyepiece scale turns through 360° to line up with the crack direction. Jain Scientific Equipments Pvt Ltd (ScienceLab) makes it as an OEM manufacturer at its own factory in Ambala, India.

Key Details

What Is a Crack Width Microscope Used For?

Crack width is one of the first things an engineer records when assessing a building, bridge or retaining wall, because it helps separate harmless shrinkage cracking from damage that needs repair. The microscope is placed on the surface over the crack, the lamp is adjusted to light the edges clearly, and the image is focused with the knob. The eyepiece scale is then rotated until its graduations sit square across the crack, and the width is read directly.

Marking each measured point and repeating readings at intervals shows whether cracks are stable or still opening, which guides repair decisions. The same instrument lets students see crack patterns from load tests on beams and slabs in the laboratory. Keep the optics clean, store the unit in a dry place, and check the lamp before site visits. It is a practical choice for engineering lab equipment used in structural and materials courses.

OEM Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) that produces this Crack Measuring Microscope at its own licensed factory in Saha, Ambala, Haryana. Colleges, survey consultants, testing laboratories, dealers and importers are supplied factory-direct, and follow-up orders or parts requests go straight to the maker — ask us.

• Concrete cover meter — locates reinforcement near cracks.

Browse all Civil Engineering Lab Equipment.

Frequently Asked Questions

What is the Crack Measuring Microscope used for?
The Crack Measuring Microscope is used to measure crack widths in concrete members, masonry walls and other structures. Engineers and students use it during condition surveys, repair assessments and laboratory load tests to record how wide cracks are and whether they change over time.

How is the scale lined up with a crack?
The eyepiece scale of the Crack Measuring Microscope can be turned through 360°, so it can be aligned with the direction of the crack or pitch under examination. This allows the width to be read squarely across the crack, whatever its orientation on the surface.

Does the microscope have its own lighting?
Yes. The Crack Measuring Microscope operates with an adjustable lamp unit that illuminates the crack, which helps when working in shaded areas, inside buildings or under bridges. The image is then sharpened by turning the focusing knob before the reading is taken.

Cementometer Moisture Meter (Product Code: SLE/CE/44) is a microwave moisture meter used to measure the moisture content of wet concrete by sensing its complex dielectric constant through a prong probe, in concrete laboratories and quality-control work. Two units cover the water/cement ratios found in wet concrete: the two-prong Type R for approximately 0.35 to 0.65, and a five-prong version for low ratios of approximately 0.25 to 0.5. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is a Cementometer Used For?

The water content of fresh concrete governs its strength and durability, yet it can drift from the design through wet aggregates or added water at the mixer. Because the dielectric constant of water is four to eight times greater than that of most aggregates and cements, changes in water content directly affect the sensor output. The Cementometer converts that output with its microprocessor and shows the moisture reading at once, so a batch can be checked before it is placed.

Insert the probe fully into a representative sample and take five to ten readings to obtain a valid average. For the highest accuracy, program the unit for the materials you actually use; the calibration routine creates these user programs on the meter itself. Stored readings, complete with time and date, can later be downloaded over USB for records. It is a useful moisture meter for any concrete laboratory looking to tighten mix control.

What to Specify When Ordering

• Which unit you need: the two-prong Type R (approx. 0.35 to 0.65 w/c), the five-prong low-ratio unit (approx. 0.25 to 0.5 w/c), or both.
• The cement types in your mixes, since the units come calibrated for standard Type I, II and III cements.
• Whether you will download readings to a PC over USB, so the software and USB connection can be confirmed on the quotation.
• The quantity and the delivery location.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, supplies the Cementometer Moisture Meter to concrete laboratories, ready-mix producers, research institutes, dealers and importers in India and international markets. As it is a branded instrument, our team sources it for you and can quote it together with fresh-concrete test sets and moulds from the ScienceLab range. See the ScienceLab profile to learn more about the company.

Related Civil Engineering Lab Equipment

Moisture readings are most meaningful when read alongside other fresh-concrete checks:

• Slump Test Apparatus — confirms workability of the batch whose water content was measured.
• Bleeding Of Freshly Mixed Concrete — shows how much mixing water rises out of the same concrete.
• K-Slump Tester — in-place workability reading in moulds and forms.
• Concrete Cube Mould — for casting cubes to link water content with strength.

Visit the Civil Engineering Lab Equipment category for more.

Frequently Asked Questions

What does the Cementometer Moisture Meter measure?
The Cementometer Moisture Meter measures the moisture content of wet concrete using a microwave sensor that reads the complex dielectric constant of the material between its prongs. An integrated microprocessor converts this and displays the moisture content directly, relating it to the water/cement ratio of the mix.

Which Cementometer unit do I need?
Two Cementometer Moisture Meter units are available. The Type R, with a two-prong probe, handles normal water/cement ratios of approximately 0.35 to 0.65, while the five-prong unit handles low ratios of approximately 0.25 to 0.5. Choose according to the mixes your laboratory tests.

Which cements is the meter calibrated for?
The Cementometer Moisture Meter units come calibrated for standard Type I, II and III cements. For the highest accuracy, the user should program the unit for the actual materials; up to ten different mix designs can be stored using the meter's own calibration process.

How many readings should be taken per sample?
With the Cementometer Moisture Meter, an average of five to ten readings is normally taken to ensure a valid result. Taking readings at different points in the sample evens out local variations caused by coarse aggregate particles near the prongs.

Can the Cementometer store and transfer data?
Yes. The Cementometer Moisture Meter can store over 150 readings, each with the time and date for future reference. Data can be recalled through a USB interface to a personal computer running the Cementometer software, which simplifies record keeping for quality-control files.

Who supplies the Cementometer Moisture Meter?
The Cementometer Moisture Meter is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources it for laboratories, producers, dealers and importers and can combine it with other concrete testing equipment on one quotation.

Test Sieves (Product Code: SLE/CE/45) are woven-wire or perforated-metal sieve pans used for sifting, filtration and particle-size grading of soils, sand, aggregates and powders in civil engineering and materials testing laboratories. They are made in sizes of 76, 100, 150, 200, 250, 300, 350 and 400 mm, among others, with frame and mesh generally in stainless steel or brass. They are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Specifications

What Are Test Sieves Used For?

Grading, the distribution of particle sizes, controls how soils compact and how aggregates pack in concrete and bituminous mixes. In a sieve analysis, a stack of sieves is arranged with the coarsest opening at the top, the dried sample is poured in and shaken by hand or on a sieve shaker, and the material retained on each sieve is weighed. The percentages passing each opening are then plotted as a grading curve.

Beyond grading, the sieves are used to sift fines out of a sample, to separate mortar or cement from coarser particles, and for simple filtration tasks. Avoid overloading any single sieve, brush the mesh gently from the underside to clear trapped particles, and dry the sieves fully before stacking them away. They are basic lab equipment for colleges, polytechnics and site laboratories in India and international markets.

What to Specify When Ordering

• The sieve size required (76, 100, 150, 200, 250, 300, 350 or 400 mm, or another size).
• Frame and mesh material: stainless steel or brass.
• Woven wire mesh or perforated metal, with the aperture openings your test method calls for.
• The number of sieves per set and the number of sets for your laboratory.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which sells under the name ScienceLab, is the OEM (original equipment manufacturer) of these Test Sieves and makes them at its own licensed factory at Saha, Ambala, Haryana. Engineering colleges, soil and aggregate laboratories, dealers and importers buy them factory-direct, and replacement sieves for an existing stack can be ordered from the same manufacturer — ask us.

What materials are the sieves made of?
Stainless steel or brass is generally used for both the frame and the woven wire mesh of the Test Sieves. The sieve frames are stamped from 22 ga sheet metal, and the wire cloth is held accurately between two die-formed frames.

What is the difference between woven wire and perforated metal sieves?
Test Sieves with woven wire cloth have square openings formed by the weave and are generally used for finer particles, while perforated metal plates have punched holes and are typically used for coarser material. State which type and aperture openings you need when ordering.

How should test sieves be cleaned and stored?
Clean Test Sieves with a soft brush from the underside, never by pushing particles through the mesh with force or sharp tools. Wash if needed, dry them completely, and store them nested in a dry place so the mesh stays taut and undamaged.

Who manufactures the Test Sieves?
Test Sieves (SLE/CE/45) are manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Quotations for single sieves or full sets come directly from the manufacturer.
