Ultrasonic Pulse Velocity Tester
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
| Parameter | Detail |
|---|---|
| Measurement | Ultrasonic transit time through the material |
| Transducer frequency | 52 kHz concrete transducers |
| Suitable materials | Highly attenuative materials including concrete, wood, stone and plastic |
| Pulse generation | High voltage applied to the transmitting transducer; wave received by the receiving transducer through the concrete |
| Investigations | Uniformity, cavities, cracks, fire or frost damage, delamination, deterioration and strength |
| Principle | Higher elastic property or strength gives a shorter transit time; weaker material gives a lower velocity |
| Product code | SLE/CE/42 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
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.

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.
Is a calibration certificate available with the tester?
