10% off · EOFY 10% Storewide Discount over $100
High-precision loop resistance tester with up to 100A DC test current for accurate measurement of low resistance connections. Ideal for switchgear, busbars, breakers, and electrical maintenance applications.
This multi-function contact loop resistance tester is a high-current micro-ohmmeter designed for accurate measurement of very low resistance values in electrical systems. It is widely used for testing contact resistance in switchgear, circuit breakers, busbar joints, cable connections, and grounding systems.
By injecting a stable DC test current (up to 100A), the instrument delivers reliable and repeatable measurements, ensuring compliance with maintenance and commissioning requirements. It is particularly suited for identifying poor connections, corrosion, or contact degradation that could lead to overheating or system failure.
The unit features a digital display with high resolution, enabling precise readings down to micro-ohm levels. Its robust design and high-power output make it suitable for demanding industrial environments including power utilities, substations, manufacturing plants, and heavy industry.
Designed for field and workshop use, the tester provides adjustable test durations and supports efficient inspection workflows for preventive maintenance and asset reliability programs.
