Galvanometer 30-0-30 mA
Product Code : LSK-PL-10320
Galvanometer 30-0-30 mA (SKU LSK-PL-10320) is a centre-zero moving coil meter reading up to 30 mA either side of zero, so students see both the size and the direction of a current. Colour-coded 4 mm socket terminals make it quick to connect in school and college practicals. The meter is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which sells directly to schools, colleges, tender contractors and distributors.
Specifications
This is a moving coil meter with a 30-0-30 mA scale, so the pointer rests at the centre and swings left or right depending on the current direction. Connections are made through colour-coded 4 mm socket terminals, and the case measures 125 x 80 x 80 mm.

Applications and Experiments for the Galvanometer 30-0-30 mA
A centre-zero galvanometer is the usual meter when current can flow either way: it shows induced currents from a moving magnet and finds the balance point in bridge circuits. The 30 mA range suits school-level induction demonstrations and general current detection on the bench.
- NCERT Class 10 science: current induced in a coil by a moving magnet.
- Class 12 physics (Electromagnetic Induction): direction of induced current and Lenz's law.
- Class 12 practicals: null detection in metre bridge and potentiometer circuits.
Standard Scope of Supply
The Galvanometer 30-0-30 mA is supplied as a single meter as described above, with its colour-coded 4 mm socket terminals. Coils, magnets and connecting leads for induction experiments are separate items that can be added to the same quotation if the lab needs them.
Packing, MOQ and Lead Time
You can ask for a single galvanometer or a quantity for every practical bench. The resulting quotation gives packing, delivery time and price for that number, and other physics lab equipment in India, such as coils, magnets or leads, can be quoted on it.
Science Lab Supplies, registered as an exporter under an Importer-Exporter Code, can ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). Enquire through the contact page or enquiry cart; the lab tender page covers tenders.
Frequently Asked Questions
What does 30-0-30 mA mean?
It means the zero is at the centre of the scale and the meter reads up to 30 mA on either side. The pointer direction therefore shows which way the current is flowing.
How is the galvanometer connected?
Through colour-coded 4 mm socket terminals, which accept 4 mm plug leads and make polarity easy to follow. The meter case measures 125 x 80 x 80 mm.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer, a science apparatus manufacturer in India with its own factory in Saha, Ambala. The galvanometer is quoted and dispatched directly from there.
Can it be used for induction experiments?
Yes. Because it is a centre-zero moving coil meter, it shows the induced current swinging one way as a magnet enters a coil and the other way as it leaves.
Related Electrical Meters and Induction Apparatus
These four items share the galvanometer's bench: a more sensitive centre-zero meter, a large demonstration meter for the whole class, an ammeter for bigger currents and an induction demonstration. Together they cover current measurement from microamperes to amperes on one quotation.
