T-212 CONTACT RESISTANCE TEST SET WITH 200A & 600A

The risk of overheating is becoming more serious due to the fact that today's distribution networks have to carry heavier loads. Checking contact resistances at regular intervals detects faults before they cause overheating. T-212 600A Contact Resistance Test Set are used to measure contact resistances in high voltage breakers, disconnecting switches (isolators), knife-contact fuses, bus joints, line joints etc.
T-212 contact resistance 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 is 10V. Display is 160*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.
