Milliammeter
Milliammeter (Product Code: SCL-373/085) is a DC current meter with a 0–500 mA range used to measure small circuit currents in education, laboratory and scientific work. It is fully enclosed in a sturdy plastic housing, has colour-coded binding posts and a zero adjustment, and is listed with an accuracy of ±2.5%. The Milliammeter is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is a Milliammeter Used For?
A milliammeter reads currents that are too small to show clearly on an ampere-range meter, such as the current through an LED, a semiconductor diode or a high resistance. In school and college practicals it is wired in series with the component, so students can see how the current changes as they vary the supply or the resistance.
Before each session, set the needle to zero with the zero adjustment, then match the colour-coded binding posts to the polarity of the supply. Include a series resistance when building a new circuit so the current stays within 500 mA, and increase the supply gradually while watching the needle.
What to Specify When Ordering
- That a 0–500 mA DC range suits your experiments, or whether a 0–5 A ammeter is also needed.
- The number of meters needed for your workbenches.
- Any leads, resistance boxes or components to be quoted alongside.
Supplier
Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, supplies this milliammeter from Ambala, Haryana, as part of its work as a physics instruments supplier in India. Schools, colleges, dealers and importers in India and international markets can source it in one consignment with ammeters, voltmeters, keys and resistance apparatus. Company information is on the profile page.

- Ammeter — a 0–5 A moving-coil meter for larger circuit currents.
- Voltmeter — measures the voltage across the component under test.
- LED — a low-current component whose current the milliammeter can show.
- Resistance Box 1-5000 Ohm Range — sets a series resistance to keep the current in range.
- Banana Plug Connectors Leads — flexible leads for connecting the meter.

Frequently Asked Questions
What range does the Milliammeter cover?
The Milliammeter covers 0 to 500 mA DC. It is intended for small circuit currents, such as those through LEDs, diodes or high resistances, where an ampere-range meter would show only a small movement of the needle.
How accurate is the Milliammeter?
The Milliammeter is listed with an accuracy of ±2.5%. For the most reliable values, set the needle to zero with the zero adjustment before use and choose circuit values that bring the reading well up the scale rather than near zero.
Does the Milliammeter have a zero adjustment?
Yes, the Milliammeter features a zero adjustment, so the needle can be reset to zero before a practical begins. Checking zero at the start of each session removes a common source of error when students record small currents.
What is the Milliammeter housing made of?
The Milliammeter is fully enclosed within a sturdy plastic housing and has colour-coded binding posts. The closed case protects the movement from dust and handling, and the colour coding helps students connect the meter with the correct polarity.
Who supplies the Milliammeter?
The Milliammeter is supplied by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab and is based in Ambala, Haryana, India. It is offered to schools, colleges, dealers and importers across India and international markets with other physics lab apparatus.
Is a calibration certificate available for the Milliammeter?
Calibration certificate availability for the Milliammeter should be discussed with us before ordering. Mention it through the contact page, and what can be provided with the meter will be stated in your quotation.
