HT9020

The HT9020 is a professional power quality analyzer with clamp meters and DYNAMIC INRUSH™ technology. It is designed to measure RMS values of DC, AC, and DC currents up to 1000 A, complying with CAT IV 600 V and IEC/EN61010-1 standards. The device measures active, reactive, and apparent power and energy, performs harmonic analysis up to the 25th order with THD% calculation in single-phase or three-phase balanced systems. It also verifies phase sequence and phase matching using a single-wire measurement method and detects events related to motor inrush currents (DYNAMIC INRUSH). DYNAMIC INRUSH™ allows measuring inrush currents with user-defined time intervals, providing more reliable results than fixed-interval testers. Users can invoke and display measurements with various time intervals, such as 16, 7, 20, 50, 100, 150, or 200 ms, enabling flexible analysis and avoiding repeated measurements. The HT9020 is supplied with a traceable calibration certificate.
