Galvanometer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11202
The Galvanometer is a laboratory galvanometer used for detecting small electric currents and observing their direction in educational electrical circuits. It is intended for students, teachers, school laboratories, colleges and STEM learning environments conducting practical work in electricity, resistance measurement, bridge circuits and electromagnetism.
Product Description
A galvanometer responds to a small electric current by producing a visible deflection. In a moving-coil design, current flowing through a coil within a magnetic field produces torque, causing the pointer to move across the scale. The direction of deflection indicates the direction of conventional current through the instrument.
The Lab Exports Galvanometer is intended for classroom demonstrations and supervised physics practicals where students must detect current, identify a null point or observe changes caused by circuit adjustments. The exact measuring range, sensitivity, scale configuration, terminal arrangement and enclosure construction must be verified for the selected model before ordering.
Key Features
Small-current detection: Provides visible indication when a low electric current passes through the connected circuit.
Directional observation: Pointer movement helps students identify changes in current direction.
Useful for null detection: Suitable for bridge and potentiometer experiments that require a zero-deflection condition.
Clear classroom demonstration: Converts an electrical response into an observable pointer movement.
Educational circuit compatibility: Intended for supervised school and college electricity experiments.
Reusable laboratory instrument: Supports repeated practical sessions when operated within its rated range.
Simple connection: Laboratory terminals allow the instrument to be inserted into an experimental circuit, subject to the supplied model.
Applications / Uses
Detecting current in low-current educational circuits.
Finding the null point in Wheatstone bridge experiments.
Using a metre bridge to compare or determine resistance.
Conducting potentiometer balance-point experiments.
Determining galvanometer resistance by the half-deflection method.
Observing electromagnetic induction and current direction.
Demonstrating the operating principle of analogue electrical meters.
How to Use the Galvanometer
Place the galvanometer upright on a stable laboratory bench.
Check that the pointer rests at zero before connecting the circuit.
Switch off the electrical supply before attaching the leads.
Connect the galvanometer according to the selected experiment diagram.
Begin with the lowest safe current and energise the circuit briefly.
Observe the direction and amount of pointer deflection.
For null experiments, adjust the circuit until the pointer returns to zero.
Switch off the supply before changing any connection.
Safety note: Never connect an unknown or high current directly to a sensitive galvanometer. Use the prescribed resistance, shunt or protective circuit and operate the instrument under teacher supervision.
Care & Maintenance
Store the instrument upright in a dry, dust-free cabinet.
Do not exceed the confirmed current range or force the pointer mechanically.
Clean the enclosure with a soft, dry cloth; do not apply liquid cleaner to the scale window.
Inspect terminals, leads and zero position before each laboratory session.

Frequently Asked Questions
What is a galvanometer used for?
A galvanometer is used to detect small electric currents and indicate their direction through pointer deflection. It is also used as a null detector in bridge and potentiometer experiments.
How does a moving-coil galvanometer work?
Current flowing through a coil placed in a magnetic field produces torque. This torque moves the coil and attached pointer against a restoring force.
Is a galvanometer the same as an ammeter?
No. A galvanometer is primarily a sensitive current detector. An ammeter is calibrated to measure current over a stated range and is designed with low effective resistance.
Why is a centre-zero galvanometer used?
A centre-zero scale allows pointer movement on either side of zero. This makes it useful for showing current direction and detecting a balance point.
Can this galvanometer be used in school laboratories?
Yes. It is intended for supervised school and college experiments involving current detection, resistance, potentiometers, bridge circuits and electromagnetic induction.
Can a galvanometer be connected directly to a battery?
A sensitive galvanometer should not be connected directly to a battery without suitable current-limiting resistance. Excess current can damage the movement.
