LCD 100A Contact Resistance Tester for Electrical Circuit Breaker Testing

Product Description

SXHL-100A Loop Resistance Tester

The SXHL-100A Loop Resistance Tester is designed to check the resistance of conductive paths in circuit breakers, busbars, and other electrical connection points. It helps engineers evaluate electrical contact conditions and supports routine inspection and maintenance of power equipment.

During testing, the instrument delivers stable constant current through the measured connection and determines its resistance from the voltage response. Four-terminal measurement technology helps minimize the influence of test lead resistance and improve measurement accuracy. The LCD touch screen provides an intuitive interface for test operation and result viewing, making the instrument suitable for laboratory and field testing.
