Micro Voltmeter
Product Code : JA-M-7879
The Micro Voltmeter (SKU JA-M-7879) is a battery-powered, multi-range voltmeter for measuring very small voltages in physics practicals and demonstrations. It has nine measurement ranges, a high input impedance of 10 megohm per volt up to a maximum of 30 megohm, and takes its input through a 4 mm socket or a UHF socket. This battery micro voltmeter for physics labs runs from a PP3 9 V battery and is manufactured in India by JaincoLab for school, college and university laboratories.
Specifications
The micro voltmeter offers nine ranges, 10 megohm per volt input impedance (maximum 30 megohm), a 4 mm or UHF input complemented by a 4 mm socket for the negative input, PP3 9 V battery power and a case measuring 208 x 155 x 115 mm.

Applications of the battery micro voltmeter
The micro voltmeter is used where the voltages of interest are too small for an ordinary school voltmeter to resolve, and its high input impedance means it draws very little current from the source being measured.
- Measuring small thermoelectric voltages from thermocouples
- Reading the output of photocells and small solar cells
- Investigating induced voltages in electromagnetic induction experiments
- Measuring potential differences across low-resistance samples
- Undergraduate electrical measurement practicals
