Low Resistance Safety Ohm Meter is a battery operated device that comes with gold plated terminals for low thermal effect. The Safety Ohm Meter is fully protected against reversal of battery polarity with a 4 wire measurement to avoid lead resistance. The Safety Ohm Meter works for hazardous areas like fuse in detonators where current should not exceed 10mA. Low Resistance Safety Ohm Meter has been equipped with safety switches and can work for long years giving optimum performance.
