Product Overview
The HM3001 Earth Resistance Tester is a high-precision instrument designed for on-site testing of earth resistance and related parameters in substations and other environments. The instrument features an integrated design with a built-in frequency-conversion power supply module, allowing for continuous, variable adjustment of the output frequency. The frequency can be set to 45 Hz or 55 Hz. Equipped with a built-in high-speed processor core and utilizing advanced digital filtering technology, it effectively mitigates interference from power-frequency electric fields, fundamentally resolving the challenge of achieving accurate measurements in the presence of strong electric field interference.
