JYL600A/300A contact resistance tester can measure contact resistance of high voltage switch and circuit breaker, also can test primar side resistance of transformer and grounding wire in groups.
1. With strong test current which can meet international standards on test of contact resistance.
2. Test can output high voltage. The test line is easy to carry with flexible field wiring.
3. Test current come from high accuracy constant-current power supply. The test processing is fast and accurate without manual adjustment.
4. We use four-pole wiring method to avoid interfer of test wire resistance on test results.
5. We set overheat protective circuit to ensure the instrument is reliable and stable in long time continuous work.
6. The instrument is simple in operation. It is suitable for outdoor work with light weight.
7. Equipped with RS485 communication interface, working with computer control software, realizing remote control measurement.
High performance of MPU (microprocessor) can provide high precise data and fast calculation:
LCD screen provide clear display for all tested value.
Thermosensitive printer provide fast and clear tested value printing.
JYR series winding resistance tester supply RS485 and USB interface for data transmission.
Testing clips are made from pure copper with punch forming , the surface is nickel plating, the handle is insulating, the testing clip is safe, easy handling and well connection.
We supply a infrared temperature measuring gun with tester for free!
KRI will supply fast delivery work to make sure your can receive tester in time!
