Product Description

Product Description

XHHL3200H Handheld contact resistance tester

 

also known as micro-ohmmeter and loop resistance tester, is an instrument to measure the contact resistance of various high-voltage switches, high-voltage circuit breakers, metal welding components, metal conductor loop resistance, and precision micro-ohm resistance.

This instrument is based on a high-speed microcontroller, combined with a high-precision A/D converter, digital measurement technology, anti-power frequency interference technology, and advanced programmable current source technology, so that the built-in large-capacity rechargeable lithium battery can generate ripple-free DC current, with a maximum output of 220A.

 

The output current can be fine-tuned in steps of 2.5A, with up to 87 current gears, to meet the test of multiple current gears;
Meanwhile, the time (10s, 20s, 30s, 40s, 50s, 60s) can be set to continuously output large current tests, which can be tested with high precision, high stability, and high intelligence in a strong interference environment; in terms of circuit design, it has functions such as open circuit protection and overheating protection.

 

 

 

XHHL3200H contact resistance tester uses a 5.6-inch color LCD display with Chinese and English operation interfaces, which are clear and intuitive. It is also equipped with standard resistors, and the instrument can be self-checked for accuracy before formal testing.

The instrument has the advantages of wide range, large data storage capacity, strong anti-interference ability, simple operation, handheld, small size, and easy to carry. A printer can also be selected for data printing.
