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.
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.
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.
