Dual Range Ammeter
Product Code : JA-M-7739
The Dual Range Ammeter (SKU JA-M-7739) is a moving coil meter for measuring direct current in school and college electricity practicals. This dual range DC ammeter reads 0–1 A and 0–5 A on a 60 mm scale with 2.5% accuracy, has a zero adjustment and connects through 4 mm socket terminals. JaincoLab manufactures it in India for physics laboratories, science departments and education buyers who need bench meters for student circuit work.
Specifications
The Dual Range Ammeter is a DC-only moving coil instrument in a 125 × 80 × 80 mm case, with two current ranges of 0–1 A and 0–5 A, a 60 mm scale length, 2.5% accuracy, a zero adjustment for setting the pointer and 4 mm socket terminals for plug leads.

Applications of the dual range DC ammeter
In school and college laboratories the ammeter is connected in series with a circuit to measure the steady current flowing through it, so students can record current against voltage, compare components and check predictions in electricity practicals from secondary classes to undergraduate physics.
- Verifying Ohm's law by recording current through a resistor at different voltages
- Measuring current in series and parallel resistor circuits
- Plotting current–voltage graphs for resistors and filament lamps
- Using the 0–1 A range for small currents and the 0–5 A range for higher-current circuits
- Teacher demonstrations of current measurement alongside a voltmeter

Frequently asked questions
What current ranges does the Dual Range Ammeter cover?
It measures direct current on two ranges, 0–1 A and 0–5 A, on a 60 mm scale with 2.5% accuracy.
Can this ammeter measure alternating current?
No. It is a moving coil instrument for DC only, so it is used with batteries and DC power supplies.
How are the leads connected?
The meter has 4 mm socket terminals, which accept standard 4 mm plug leads used in school circuit work.
What should a quotation request include?
Send the SKU JA-M-7739, the quantity, any voltmeters or galvanometers needed for the same laboratory and the delivery destination.
