The Metravi PRO 8220 Micro Ohms Meter is designed to measure the Contact Resistance of various high voltage switches and circuit breakers, connection resistance of metal welding components, metal conductor Loop Resistance and precision Micro Ohm Resistance. With a high speed micro-controller at the core, the device combines high precision A/D convertor, digital measurement technology, anti-power frequency interference technology, and advance program-controlled current source technology, so that the built-in, high capacity, rechargeable Lithium batteries product no ripples.

Maximum output is 220A DC and the output current can be fine-tuned every 2.5A steps, up to 87 current gears, to meet the Multi-current Gear Test. At the same time, the user can set the time (10s, 20s, 30s, 40s, 50s, 60s), continuously output large Current Test and can test with high precision, high stability and high intelligence, even in strong interference environments.

The instrument features circuit protection and overheat protection. It comes with a 5.6 inch large, colour, LCD display, which is clear and intuitive. Equipped with standard resistors, the accuracy of the instrument can be self-inspected before the formal test. Wide-range, large Data Storage capacity, strong anti-interference ability and simple operation make this handheld, small size, easy-to carry device, a valuable tool for the field. It can also be equipped with printer for data printing (optional).
