Galvanometer
Product Code : LSK-LM-11125
Galvanometer (SKU LSK-LM-11125) is an analogue centre-zero demonstration meter reading −500–0–500 µA, used to detect small direct currents and show which way they flow. It suits physics and electronics teaching in school, college and diploma laboratories. Each meter is built and finished by Science Lab Supplies at its manufacturing site on Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and goes out to schools, colleges, tender contractors and distributors on direct factory quotations.
Specifications
The table lists the range, accuracy, casing and terminals of the centre-zero galvanometer one by one. In short, it reads −500–0–500 µA of direct current with ±2.5% accuracy, sits in a sloped plastic desk-stand casing and connects through positive and negative binding posts.

Applications and Experiments for the Centre-Zero Galvanometer
Because the pointer rests at the centre, the galvanometer shows both the size and the direction of a small current. As a school galvanometer in India, it suits induction demonstrations and null-point experiments in Class 12 physics, and teaching work in B.Sc. and diploma electrical labs.
- Class 12 physics: Faraday's experiments, showing induced current as a magnet moves in a coil, for example the 700-turn and 1150-turn coils of the Apparatus for Studying the Production of Electricity by Induction.
- Finding the balance point in meter bridge and potentiometer experiments, such as those built from the Potentiometer Kit.
- Demonstrating that reversing a connection reverses the current direction.
- Diploma and B.Sc. labs: introducing microampere-level DC measurement.
Standard Scope of Supply
The Galvanometer is supplied as a single meter in its sloped plastic desk-stand casing with positive and negative binding posts, as described above. Connecting leads, coils and resistance boxes are separate items that can be added to the quotation.
Packing, MOQ and Lead Time
Ask for a quote for one galvanometer or for enough meters to equip every bench. We state packing, delivery time and price for the quantity you give, and leads, resistance boxes and other physics lab equipment in India from our catalogue can be combined on that quotation.
Registered as an exporter under an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. A meter count for your electricity benches is all we need: send it via the contact page or the enquiry cart, and use the lab tender page if the order is part of a bid.
Frequently Asked Questions
What is the range of this galvanometer?
It reads from −500 µA through zero to +500 µA DC, with an accuracy of ±2.5%, so small currents in either direction can be seen on the same scale.
Why is a centre-zero meter used for induction experiments?
Induced current changes direction as a magnet enters or leaves a coil. A centre-zero pointer swings left or right, so students see the direction change as well as the size of the current.
Is Science Lab Supplies the manufacturer or a trader?
The company's own factory in Saha, Ambala, India, produces this galvanometer, which makes Science Lab Supplies the manufacturer; every price and delivery date you receive is therefore quoted by the maker directly.
Can it measure AC?
The meter is built to detect and measure small direct currents in microamperes. For AC work, ask through the contact page about a suitable meter from the range.
