Portable Transformer High-Voltage Switch Micro-Ohm Resistance Tester 200A Contact Resistance Testing

Product Description

Handheld 200A contact resistance tester XHHL3200SC

Product Description

The loop resistance tester, also known as the micro-ohmmeter and contact resistance tester, is an instrument developed by our company for measuring various high-voltage switches, high-voltage circuit breakers, metal welding components, metal conductor loop resistance, and precision micro-ohm resistance.

 

1. This instrument has a built-in large-capacity rechargeable lithium battery to generate ripple-free DC current, with a maximum output of 220A. The output current can be fine-tuned in 2.5A steps, with up to 87 current gears, which can meet the test of multiple current gears;

2. At the same time, the time (10s, 20s, 30s, 40s, 50s, 60s) can be set to continuously output large current tests, and high-precision, high-stability, and high-intelligence tests can still be performed in a strong interference environment;

3. It has open circuit protection, overheating protection and other functions.

4. The instrument uses a 5.6-inch color LCD display and an English operation interface.

5. The standard resistance of the system can be self-checked before the formal test to ensure accuracy.

6. Wide range, large data storage capacity, strong anti-interference ability, simple operation, handheld, and easy to carry. An optional printer is also available for data printing.
