RS232 Portable Circuit Breaker 100A Contact Resistance Test Equipment
T-212 Portable Circuit Breaker 100A Contact Resistance Test Equipment
T-212 contact resistance MicroOhm Meter tester adopts the top open structure or vehicle mounted horizontal chassis. It has that vantage: more small volume, more light weight, more strong functions, and the simple operation. It designed for field tester design. The high output voltage is10V. Display is160*128 large LCD screen. Test current optionally, test time can be set, test process dynamic tips, suitable for different working environment. It can save 200 test record, the records can be printed and uploaded to the computer.
We ensure that our Contact Resistance tests sets are portable, making them suitable for field measurements. Our contact resistance testers’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum. T-212 100A Circuit Breaker Contact Resistance Test Equipment According to the requirements of the new power Preventive testing procedures, conductive loop resistance testing of various switching devices is must be measured, whose testing current can not be less than 100A, Continuous Current time shall not be less than one minute.
We are offering Contact Resistance Micro Ohm Meter to our clients.
