Contact Resistance Tester 600A

Contact resistance tester HYHL-600A 400A and 600A are same panel design. Contact resistance tester output DC 100A/400A/600A current to test the sample resistance. It is designed according to IEC62271. The main application of the tester is measurement of circuit breaker contact resistance. All the test results of the tester could be print by the micro-printer which is integrated in the tester. Also all the test results saved in the tester could be upload to PC computer and
