Micro Ohm Meter
We are catering to the needs of the electrical industry by manufacturing and supplying a wide range of Micro Ohm Meter. These meters are ideal for measuring the resistance of bus bar joints, male-female contacts of isolators and circuit breakers. We use optimum quality of components, sourced from the authentic vendors to manufacture the meter. Our Micro Ohm Meter available with LED display with hold facility, operates at the normal 240volts.
Portable to carry
Micro Ohm Meter
Compact and portable. Contact Resistance Meter is meant for measurement of resistance of bus bar joints, male-female contacts of isolators, SF-6 Breaker contacts, GTS breaker contacts etc. of the sub-stations. The measurement of contact resistance is done by applying a DC current of 0-100 Amps. and measuring the voltage drop a across the contacts. An ammeter and a millivoltmeter (Micro-ohmmeter) are provided measuring the current and resistance. A lamp indicates the AC supply position. A variac is provided for adjusting the output current from 0 to 100 amps. Fuse for protection against overload is incorporated.
