The HVM100 and HVM200 handheld micro-ohmmeter is a highly precise instrument designed to measure extremely low electrical resistances, often in the micro-ohm range. It is essential for ensuring the integrity and reliability of critical electrical connections and components. Typical applications include:

Contact resistance tests of high-voltage switches and circuit breakers, to confirm proper conductivity and identify deterioration that could lead to overheating or failure.

Connection resistance tests of welded, bolted, or clamped metallic joints, verifying the quality of electrical bonding and detecting hidden faults. Circuit resistance tests of busbars, cables, and conductors, ensuring low-loss current flow across power distribution systems.

Precision low-resistance measurements in manufacturing, maintenance, and quality control, where even minor increases in resistance can indicate defects or potential hazards.

By detecting small increases in resistance, a micro-ohm tester helps prevent equipment failures, reduces downtime, and enhances overall system safety and performance..
