Millivoltmeter
Millivoltmeter (Product Code: SCL-535/017) is an analog meter with a 0–15 mV range used to measure very small potential differences in school and college chemistry and physics practicals. Its unbreakable plastic body, ±2% accuracy and included 4 mm stackable plug lead make it a sturdy choice for students reading signals too small to show on an ordinary voltmeter. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Millivoltmeter Used For?
Millivolt-level signals turn up in several standard practicals: the output of a thermocouple as one junction is heated, the potential drop across a short length of wire or a low-value resistor carrying a small current, and small differences studied in some electrochemistry demonstrations. The meter is connected across the points of interest with the stackable 4 mm lead, so further connections can be plugged on top without disturbing the circuit, and the analog needle lets students watch a reading rise or fall as conditions change. A dedicated millivolt scale removes the guesswork of reading tiny deflections on a volt-range meter, which is why it belongs on the list of physics lab instruments for electricity experiments.
Because the full scale is only 15 mV, never connect the meter directly across a battery, cell or power supply output; set up the circuit first, keep the current low with a rheostat, and connect the meter last. Observe polarity, read the scale straight on to avoid parallax, and store the meter flat in a dry cupboard. The unbreakable plastic body copes well with everyday handling by students.
OEM Manufacturer
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this millivoltmeter. The meter is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and goes factory-direct to schools, colleges, dealers and importers in India and international markets rather than through a trading chain.
Buying from the manufacturer keeps quotations, repeat orders for extra lab benches and questions about replacement leads in one place – ask us and the factory answers directly. See the ScienceLab company profile for more.

These items are commonly used with a millivoltmeter in the same circuit or as alternatives for other ranges:
- Galvanometer — a centre zero meter for null-point and current-direction work.
- Micro Voltmeter — an option for even smaller signals.
- Analogue Voltmeter — for readings well above the millivolt range.
- Rheostat — to limit and adjust the current in the circuit.
- Connecting Wire — for wiring up the rest of the experiment.

Frequently Asked Questions
What is the measuring range of the Millivoltmeter?
The Millivoltmeter measures 0–15 mV on an analog scale. That full-scale value suits thermocouple outputs and small potential drops across wires or low-value resistors, readings that would barely move the needle of an ordinary volt-range meter.
How accurate is the Millivoltmeter?
The stated accuracy of the Millivoltmeter is ±2%, which is suited to student practicals and demonstrations. For a detailed accuracy statement or test data for a tender, please ask through our contact page before ordering.
What connection lead comes with the Millivoltmeter?
The Millivoltmeter is supplied with a 4 mm stackable plug lead. Stackable plugs let further leads be plugged onto the same connection point, so the meter can be added to or removed from a circuit without undoing other connections.
Can the Millivoltmeter measure the voltage of a cell?
No. A single cell produces far more than 15 mV and would overload the Millivoltmeter's scale. Use a voltmeter with a volt range for cells and power supplies, and keep this meter for millivolt-level signals.
Who manufactures the Millivoltmeter?
The Millivoltmeter is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers buy it factory-direct, with quotations issued by the manufacturer.
Is a calibration certificate available for the Millivoltmeter?
Calibration certificate availability for the Millivoltmeter is not stated in the listing. Please discuss your documentation needs with us when you enquire, so we can advise before the quotation is prepared.
What does an institutional quotation for the Millivoltmeter need?
To quote the Millivoltmeter, we need the quantity, the delivery location and any tender or specification reference. We supply schools, colleges and distributors in India and international markets and reply with a formal quotation.
