200A Contact Resistance Meter

Model: CRM-200

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.
