100A Loop Resistance Tester – Handheld Contact Resistance Meter
High-current loop resistance tester for accurate measurement of contact resistance in switchgear and electrical connections. Portable unit with built-in printer for field reporting.
This handheld loop resistance tester is designed for precise measurement of contact resistance in electrical systems, using a high test current of up to 100A. It is an essential tool for assessing the condition of circuit breakers, switchgear, busbars, and electrical joints.
By applying a high current and measuring voltage drop, the instrument accurately determines resistance values, helping identify loose connections, corrosion, or degradation that can lead to overheating and failure.
The unit features a clear digital display for real-time readings and an integrated printer for immediate test reports, making it ideal for maintenance teams, commissioning engineers, and field technicians.
Its portable, battery-powered design ensures ease of use in substations, industrial facilities, and on-site testing environments.
