HT Italia HT9020 Clamp Meter with Measurement of Powers/Harmonics and Inrush Currents

The Ht Italia HT9020 have been designed for measuring DC, AC+DC TRMS current up to 1000A to obtain CAT IV 600V in compliance with standard IEC/EN61010-1
It also measure Active, Reactive and Apparent Power, Energy, voltage/current harmonic analysis up to the 25th with THD% calculation in balanced single-phase or three-phase systems. They also allow testing phase sequence and concordance with the 1-terminal measuring method. It is also possible to detect the events linked to motor starting (INRUSH) currents.
