CR.200A

The CR.200A is a portable, microprocessor-controlled contact resistance tester designed in compliance with IEC 62271 standards for the accurate measurement of circuit breaker contact resistance and high-current cable joints. With selectable DC test currents up to 200 A, it delivers fast, stable, and precise results in field and laboratory applications.

The instrument features a true colour LCD touchscreen for easy operation, built-in data storage, and integrated printing for onsite reporting. Test results can also be transferred to a PC via RS232 or USB for report generation. Compact and lightweight, the CR.200A is engineered for portability and reliability.
