Product introduction

NRJJ-Ⅱ automatic insulating oil dielectric strength tester is based on the international IEC-156 and international GB507-86 "insulating oil dielectric strength test" requirements, combined with the majority of users feedback, and then developed the fifth generation of full-automated instrumentation. The 16-bit micro-controller as the core control unit, all operations can all be preset, automatic calculate the average breakdown value, several breakdown times with good repeatability. Solve the problem of crashing easily, It will carry a delivery test with 50 times continuously breakdown, no any crash at all.
