Microhmmeters

The ASGT-600 Safety Ground Tester is a 600A DC micro-ohmmeter designed specifically to measure the resistance of protective in-service grounding and jumper cable assemblies. The ASGT-600 can measure the resistance of the grounding cables, clamps and ferrules. The measured resistance values can be compared against the calculated values (using the ASTM 2249-03 standard) and a Pass/Fail result can be printed along with the measured resistance values.

Safety Ground Tester ASGT-600

Amperis Products S.L. has several microhmmeter models, according to your needs.
All our models are designed for testing resistance in welding joints, HV circuit-breakers (according to IEEE C57.09-1999 5.15), or for any low-resistance measuring application.

The QMOM-600 is specifically designed for testing EHV circuit-breaker contact resistances, bushing contact joints, welding joints, or for any low-resistance measuring application. This high current and very lightweight (33 lbs/ 15 Kg) micro-ohmmeter is designed to meet the IEEE C57.09-1999 (5.15) requirement for testing circuit breaker contact resistance.

The QMOM-200 S3 can accurately measure resistance values from 1 micro-ohm to 5 ohms. A 0.1 micro-ohm resolution is possible with current greater than 5A. The QMOM-200 S3 applies a selectable true DC test current from 1A to 200A to the resistance load to be tested.

Microhmmeter QMOM 200 S3

The QAUTO-OHM 200 S3 is Amperis’ fourth generation, microprocessor-based, true DC micro-ohmmeter. It is designed for testing EHV circuit-breaker contact resistances, bushing contact joints, welding joints, or for any low-resistance measuring application.
