Handheld Loop Resistance Tester – 100A Portable Micro-Ohmmeter for Switchgear
Compact 100A handheld loop resistance tester designed for fast, accurate measurement of contact resistance in circuit breakers, busbars, and electrical connections.
This handheld loop resistance tester is a portable high-current micro-ohmmeter designed for measuring very low resistance values in electrical systems. It is ideal for testing contact resistance in circuit breakers, switchgear, busbars, cable joints, and grounding connections.
With a built-in high-current output of up to 100A, the unit ensures accurate and repeatable measurements by minimising the effects of contact resistance variability. Its handheld design and integrated battery make it well suited for field use, enabling technicians to perform testing without reliance on mains power.
The tester provides clear digital readings, allowing for quick identification of poor connections, oxidation, or degradation that could lead to overheating or equipment failure. It is widely used in power utilities, substations, industrial plants, and maintenance operations.
Designed for ease of use and portability, this instrument supports efficient commissioning, routine inspection, and preventative maintenance programs.
