Contact Resistance Meter CRM-200 can provide test current up to 200A subject to the load resistance and supply voltage, which is suitable for testing circuit breaker contacts, switch contacts, busbar joints or other applications where high current is needed.

Contact Resistance Meter CRM-200 uses a four terminal measurement method to eliminate the resistance of the test leads from the measurement.

The main features of Contact Resistance Meter CRM-200 are as follows:

●Max. test current: 200A DC

●0.1µΩ resolution  

●Touch screen for operation

●7” colour LCD screen display

●On board memory for saving 1000 test results   

●Download test results via USB interface  

●Print the test result directly via built-in thermal printer
