MIT525 5 kV DC Insulation Resistance Testers - Beijing Kanggaote Instruments and Equipment

Product introduction

The MIT525 5 kV insulation resistance tester is a CAT IV rated, compact tester for the diagnostic testing and maintenance of high voltage electrical equipment. Enclosed in a tough case, it is both smaller and lighter than its predecessor making it even easier to carry and store. The MIT525 comes with all test modes including a ramp test plus advanced memory functions with recall to screen, RTC for time/date stamp of results, and USB drive to PC/PowerDB.

As well as measuring insulation resitance to 20 TΩ, the MIT525 also offers various diagnostic tests such as polarisation index, dielectric absorption ratio, step voltage, dielectric discharge, and ramp testing.
The MIT525 is also equipped with lithium-ion fast rechargeable batteries and has a large, clear, easy-to-read, display making it equally suitable for use in both bright sunlight and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status, and time constant. In addition, the elapsed time of the test is displayed constantly, removing the need for separate timer.

▪ Measures up to 10 TΩ
▪ PI, DAR, DD, SV, and ramp test
▪ Improved productivity – operate from line power/mains if battery dead
▪ Li ion battery - extended capacity, rapid charge
▪ Advanced memory with time/date stamp
▪ CATIV 600 V safety rating

The Insulation Resistance (IR) test is a quantitative test, which indicates the effectiveness of a product’s electrical insulation. Applications include cables, transformers, motors / generators, circuit breakers and bushings. Common insulation tests are the “spot test”, a 1 minute IR test and a 10 minute Polarisation Index (PI) test, where PI is the ratio R10 min / R1 min and is temperature independent.
