Galvanometer 50-0-50mV
Galvanometer 50-0-50mV (Product Code: SLE/PHY/181) is a centre-zero moving coil meter with a 50-0-50 scale, used for DC-only readings that can swing either side of zero in school and college electricity practicals. Its colour-coded 4 mm socket terminals make it a quick-to-wire galvanometer for school labs in India. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India; please confirm the range unit (mV or mA) when ordering, as explained below.

What Is the 50-0-50 Galvanometer Used For?
With its pointer resting at the middle of the scale, this meter shows both the size and the direction of a small DC reading. Typical uses are electromagnetic induction demonstrations, where a magnet pushed into a coil and pulled out swings the needle one way and then the other, and null-point detection in bridge and potentiometer circuits.
Connect it only to DC circuits and follow the colour coding on the terminals. When trying a new circuit, put a rheostat or high resistance in series first so the pointer stays on scale, then reduce it gradually. It pairs naturally with the coils and magnets of an electromagnetic induction kit.
What to Specify When Ordering
- The range unit you need — millivolts (as in the product name) or milliamps.
- Quantity, for example one meter per practical bench.
- Any connecting leads, rheostats or low-voltage power supplies to quote together.
Supplier
