Galvanometer Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12361

The Galvanometer is a sensitive physics laboratory instrument used for detecting small electric currents and showing current direction through pointer deflection. It is designed for school physics labs, college practical rooms, STEM classrooms, and teacher-led current electricity demonstrations requiring visible current detection.

Product Description

The Galvanometer by School Equipments helps students observe the presence and direction of small current in an electrical circuit. In classroom experiments, the pointer deflection gives a clear visual indication when current flows through the meter coil.

This instrument is suitable for current electricity, electromagnetic induction, meter conversion, bridge circuits, and null-point experiments. It may be used with resistance units, shunts, cells, keys, and connecting leads, depending on the experiment. Exact range, internal resistance, sensitivity, scale type, and protection features should be confirmed before publishing.

Key Features

• Designed for detecting small current in school and college physics laboratories.
• Useful for showing direction of current through left or right pointer deflection.
• Supports experiments on galvanometer deflection, null point, and circuit continuity.
• Can be used in Wheatstone bridge, potentiometer, induction, and meter conversion practicals.
• Suitable for teacher demonstrations and student hands-on electricity experiments.
• Compatible with shunts and multipliers only when the supplied meter rating permits it.
• Range, accuracy, sensitivity, and terminal configuration should be verified from the final model.

How to Use the Galvanometer

1. Place the galvanometer on a stable, dry laboratory bench.
2. Check that the pointer is at zero before connecting the circuit.
3. Connect the galvanometer in the circuit as shown in the experiment diagram.
4. Use a low-current source and suitable resistance to protect the meter movement.
5. Observe the direction and size of pointer deflection when current flows.
6. Reverse the current direction, if required, and compare the deflection direction.
7. Switch off the circuit before changing connections or adding shunts.

Safety note: never connect a sensitive galvanometer directly across a high-current source. Use protective resistance, shunts, or teacher-approved circuits only.

Care & Maintenance

• Store the galvanometer in a dry place to protect the scale and moving system.
• Do not overload the meter beyond its confirmed current rating.
• Keep the instrument away from mechanical shock, dust, and strong external magnets.
• Check terminals, pointer zero, and lead condition before each practical session.

Frequently Asked Questions

What is a Galvanometer used for?

A Galvanometer is used to detect small electric currents and show the direction of current through pointer deflection in physics experiments.

Is this galvanometer suitable for school physics laboratories?

Yes. It is suitable for school physics labs, college practical rooms, STEM classrooms, and teacher-led current electricity demonstrations.

Can a galvanometer measure current directly?

A galvanometer detects small current. For larger current measurement, it must be used with a suitable shunt resistance if the final meter design permits conversion.

Can this galvanometer be converted into an ammeter?

Yes, a galvanometer can be converted into an ammeter by connecting a suitable low-resistance shunt in parallel, but the shunt value must match the meter rating.

Can this galvanometer be used in Wheatstone bridge experiments?

Yes. A galvanometer is commonly used as a null detector in Wheatstone bridge experiments to identify the balance condition.

What category should this product be listed under?

This product should be listed under physics laboratory equipment, electricity and electromagnetism apparatus, current detection instruments, and analogue measuring instruments.
