HR100A Handheld Contact Resistance Tester

Handheld structure for easy carrying. Suitable for practical use where portability is required.

FEATURES:

1. Handheld design for easy portability;
2. Measures the resistance of the circuit breaker’s main contacts, the disconnector contacts, and the busbar connection parts;
3. Selectable output current timing: 1s, 3s, and 60s;
4. Allows entry of the equipment number to review stored test data after testing;
5. Supports local storage and U-disk data transfer;
6. Stores up to 100 groups of test data for long-term use;
7. Supports printing of test data using an external Bluetooth printer;
8. Built-in calendar clock records the test date;
9. Provides an automatic shutdown function after 200s without operation;
10. Built-in large-capacity lithium battery—no external power supply required during testing.
