Ammeter
Ammeter (Product Code: SCL-371/084) is a moving-coil DC ammeter with a 0–5 A range used to measure the current flowing in circuits during school and college physics practicals. It stands on a square-based desk stand with lock-type terminals and is specified to an accuracy of ±2.0% of full-scale deflection. The Ammeter is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is a Moving Coil Ammeter Used For?
The ammeter is placed in series in a circuit so that the whole current passes through it, which makes it essential for Ohm’s law, series and parallel resistance and rheostat current-control experiments. Its 0–5 A range handles the larger currents drawn by low-resistance circuits, while a milliammeter is the better choice for very small currents.
As a staple of physics lab equipment for schools in India, it should be wired with its positive terminal towards the positive side of the supply and never connected straight across a cell. Because the ±2.0% accuracy is quoted on full scale, readings in the upper part of the dial are proportionally more precise, so adjust the rheostat to bring the needle well up the scale.
What to Specify When Ordering
- That a 0–5 A DC range suits your experiments, or whether a milliammeter is also needed.
- The number of ammeters required for your workbenches.
- Any matching voltmeters, rheostats, keys or leads to include in the same quotation.
OEM Manufacturer
ScienceLab is the brand of Jain Scientific Equipments Private Limited, and this Ammeter is one of the meters the company builds itself, as OEM, at its factory in Saha, Ambala, Haryana, India. Meters leave the factory directly for schools, colleges, dealers and importers, so questions about replacement parts or repeat batches go straight to the maker — just ask us. Company details are on the ScienceLab profile.
Related Physics Lab Equipment
Apparatus normally wired into the same circuit as the ammeter:
- Voltmeter — reads the potential difference while the ammeter reads current.
- Milliammeter — a lower-range meter for currents in milliamperes.
- Rheostat 30 Ohm — adjusts the circuit current to bring readings up the scale.
- One Way Key — switches the circuit on only while readings are taken.
- Resistance Box — provides known resistances for current measurements.
The Physics Lab category lists the remaining meters and circuit apparatus.
Frequently Asked Questions
What are the range and accuracy of the Ammeter?
The Ammeter reads DC current from 0 to 5 A with a stated accuracy of ±2.0% of full-scale deflection (F.S.D.). Because the error is quoted on the full scale, readings taken in the upper part of the scale are relatively more precise than readings near zero.
How should the Ammeter be connected in a circuit?
The Ammeter must be connected in series so that the whole circuit current passes through it, with its positive terminal towards the positive side of the supply. Never connect it directly across a cell or power supply, as the meter’s very low resistance would allow a damaging current.
What type of movement does the Ammeter use?
The Ammeter uses a moving-coil movement designed for direct current, so the needle deflects in proportion to the current flowing through the coil. Moving-coil meters respond to DC only, which is why the Ammeter should not be connected to an AC supply.
How is the Ammeter mounted on the bench?
The Ammeter comes on a desk stand with a square-shaped base and lock-type terminals. The stand keeps the meter steady and upright on the workbench, and the lock-type terminals hold connecting wires or leads securely while students take their readings.
Who manufactures the Ammeter?
The Ammeter is manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct, so quotations and follow-up questions are handled by the manufacturer rather than a trader.
Can the Ammeter be ordered for a whole laboratory?
Yes, the Ammeter can be ordered in bulk for school and college laboratories, dealers and tender supplies in India and international markets. Share the quantity, the delivery location and any matching voltmeters or rheostats, and the manufacturer will quote for the complete set.
