Galvanometer
Galvanometer (Product Code: SCL-537/018) is a centre zero moving coil meter with a 50 µA–0–50 µA range, used to detect small currents and show their direction in physics and chemistry practicals. Students use it as the null detector on meter bridges and potentiometers, and its 1000 ohm movement has diode protection against overload up to 12 V DC. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Centre Zero Galvanometer Used For?
The centre zero scale is what makes this meter useful for balance experiments. On a meter bridge, Wheatstone bridge or potentiometer, students slide the jockey along the wire and watch the needle swing one way, then the other, until it rests at zero; that null point gives the balancing length from which resistance or EMF is calculated. Because the needle deflects in either direction, it also shows the changing direction of an induced current when a magnet is pushed into and pulled out of a coil, the kind of slow AC indication it is suited to.
For bridge work, start with a high resistance in series or a shunt across the meter, tap the jockey rather than dragging it, and remove the protection only when close to balance. The diode protection against overload up to 12 V DC adds a margin for mistakes, but students should still check the circuit before closing the key. Store the meter flat and away from strong magnets so it stays a dependable part of your physics lab equipment in India.
OEM Manufacturer
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of this centre zero Galvanometer and builds it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers buy it factory-direct, and questions about servicing or repeat orders go straight to the manufacturer — just ask us.
Buyers completing vendor forms can use the company’s GSTIN 06AAECJ8618A1ZT and Legal Entity Identifier 3358004HRD1JIVXKYX49. Further details are on the ScienceLab company profile.
Related Laboratory Equipment
The galvanometer is normally used with the following apparatus in the same experiment:
- Meter Bridge — finds unknown resistance using the galvanometer as null detector
- Wheatstone Bridge Apparatus — the classic balance circuit for this meter
- Potentiometer — compares EMFs by finding the balancing length
- One Way Key — switches the circuit on only while a reading is taken
- Milli Voltmeter — for measuring small potential differences rather than detecting a null
More meters and apparatus are listed in the Chemistry Lab category.
Frequently Asked Questions
What is the range of this Galvanometer?
The Galvanometer (SCL-537/018) reads 50 µA–0–50 µA with zero at the centre of the scale, so the needle deflects either way and shows the direction of a small current as well as its presence.
What is the coil resistance of the Galvanometer?
The Galvanometer has a 1000 ohm moving coil movement. Knowing this value helps students choose a suitable shunt or series resistance when they convert a galvanometer into an ammeter or voltmeter in practical work.
Is the Galvanometer protected if a student connects it wrongly?
The Galvanometer has diode protection against overload up to 12 V DC, which adds a margin for wiring mistakes. A series resistance or shunt is still recommended until a bridge or potentiometer circuit is close to balance.
Can the Galvanometer be used with AC?
The Galvanometer is suited to use as an indicator in slow AC, such as induced currents that reverse direction slowly when a magnet moves in a coil. It is not intended for measuring mains AC.
Is a calibration certificate available?
Calibration certificate availability for the Galvanometer should be raised with us at the enquiry stage. Mention it through our contact page together with your quantity, and we will advise before preparing the quotation.
Who manufactures the Galvanometer?
The Galvanometer (SCL-537/018) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to institutions, dealers and importers.
Can you quote for a full physics or chemistry lab?
Yes. Share the number of Galvanometer units, the delivery location and any tender reference, and the manufacturer will quote for institutions and distributors in India and international markets, with bridges, keys and potentiometers if needed.
