MOM600A 600A Micro-ohmmeter
The MOM600A is a 600 A micro-ohmmeter designed for measure contact resistances in high voltage circuit breakers, disconnecting switches (isolators), knife-contact fuses, bus joints, line joints etc. It is incredibly tough and hardwaring, able to be used in wide range of temperatures, so if you're working in the artic or the tropics, this machine will operate just as efficiently in the field. To that end, the complete unit includes a set of highly flexible cables (including separate measurement cables) and a sturdy transport case.
