Digital Micro OHM Meters 

Our range of digital micro OHM meters is a compact and high reliability 31/2 digit instrument suitable for measurement of resistivity of copper wires from 7/0 SWG to 50 SWG, resistance of cables, windings, coils, heater elements and contact resistance of switches, relays, etc. Emphasis is provided to the designing of the instrument in order to ensure quick, stable and repeatable readings of resistance. The instrument uses 4-terminal measurement so that resistance of test leads and contacts is eliminated from test results. Actual value of resistor is directly displayed on seven segment 12.5 mm display.

The technical specifications are as follows: Range of Measurement:

1micro-ohm to 1999 ohm in seven range
