For all your test equipment requirements

HT Italia PQA824 Three-phase and Single-phase Power Quality Analyzer.


Measure, record, analyze power quality on electrical installations with the 800 series meters from HT ITALIA. The PQA824 is completely designed in Windows CE technology permitting an easy and fast analysis of large quantities of data.

The unit has an innovative graphic color TFT “touch screen,” and a wide display that will meet all requests from any electrical verifier. The interface is user-friendly and help is available from each screen. A vectorial diagram feature, allows evaluation of phase angles between voltages and currents in order to understand the inductive or capacitive nature of loads on an installation.

An internal memory of 15Mbytes allows the saving of parameters and recording data over extended periods of time. The model has an USB interface to PC for the downloading and analysis using dedicated TOPVIEW Windows software. The PQA824 also permits detection of fast voltage transients and with a minimum resolution of 5µs (200kHz) and adjustable trigger thresholds.  The model has rechargeable  Li-Ion battery or can be used on the mains with the external 100/240V AC adapter.

The PQA 824 comes with four HTFLEX33E Flexible 3000A clamps (174mm diameter)
