Contact Resistance Electrical Test Equipment Micro Ohm Meter Tester With Printer
T-212 Contact Resistance DC 200A MicroOhm Meter Tester with Printer
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.
