HT Italia PQA820 Three-phase Power Quality Analyzer

HTI Auth Large

HT Italia PQA820 is a three-phase power quality analyzer and energy logger performing an easy and wide analysis of the most significant parameters of the electrical system. Thanks to an innovative project, the instrument can be interfaced to smart phones, tablets and PDAs (iOS and / or Android) meeting the requests of the most demanding professionals. All the electrical parameters can be displayed in both numerical and graphical mode, by waveforms, histograms and phasors. The vector diagram shows the phase angle between any voltage and the related current, revealing the inductive or capacitive nature of the loads connected.

The HT Italia PQA820 large built-in memory allows to log up to 383 parameters, granting a recording lasting more than one month with integration period of 10 minutes. The HT Italia PQA820 three-phase power quality analyzer records all parameters by default so avoiding any failure. The user will never miss recording the parameters he needs, since the HT Italia PQA820 records everything while selecting one of the three predefined settings (single-phase, 3 phase without neutral, 3-phase with neutral).

The HT Italia PQA820 three phase energy logger is powered by an internal rechargeable Li-ion battery with built-in user-selectable L-N or L-L power supply. The Wi-Fi and the USB interfaces grant connection to smart phones, tablets, PDAs and PCs for instrument setting, recording start and stop, data downloading and data analysis. Its IP65 waterproof hard carrying case allows the HT Italia PQA820 instrument to work outdoors under critical environmental conditions..
