PQA823 HT Instruments Power Analyzer

The PQA823 is a Power Analyzer from HT Instruments. A power analyzer, or power quality analyzer, can take accurate measurements of direct current DC, alternating current AC, voltages, phase rotations, and power in many different types of electronic equipment. Engineers can test power supplies, industrial machinery, motor drivers, home appliances, and office equipment with used and refurbished power analyzers.

The power quality analyzer and energy logger HT  PQA823 permits an easy and wide fast analysis of a huge quantity of data any other system. Thanks to an innovative design and a graphic colour TFT "touch screen" wide display these models finally meet all requests from any exigent electrical verifier. The interface it's incredible "user-friendly" due to the intuitive icon selection of any kind of feature and a contextual help it's available for each screen.
The model permits the visualization of all parameters both in numeric and graphical mode with large use of waveforms and histograms (for harmonic analysis) screens. The vectorial diagram feature permit also to evaluate the mutual phase angle between voltages and current in order to understand the nature inductive or capacitive of the loads on an installation.

The power quality analyzer and energy logger PQA823 have a great internal memory in order to save recording results for a lot of parameters (e.g: >3 weeks for 251 parameters and integrated period of 15 minutes), but this memory can be expanded by using of external compact flash cards fitted on meters. Pen drives USB connection it's also available in order to transfer recordings from meter and realize a practical and sure portable situation of all date. PQA823 meter are powered by a internal rechargeable Li-Ion battery which permits complete operation for more than 3 hours and are external supplied by using a 100/240V AC adapter. USB interface permits the connection with PC for download and analysis of recordings with dedicated TOPVIEW software.
