Chauvin Arnoux CA8331 Qualistar+ Power Analyser
The Chauvin Arnoux CA8331 Qualistar+ Power Analyser gives you a clear way to check power quality on complex electrical systems. It helps you view key electrical values fast, so you can test, log and review results with less effort.
Built for practical site work, this model has four current inputs and three voltage channels. As a result, the Chauvin Arnoux CA8331 Qualistar+ Power Analyser can monitor several values at the same time while keeping readings easy to follow on its high-contrast colour screen.
Power quality performance
It measures true-RMS AC and DC voltage, true-RMS AC and DC current, frequency, power and energy values. In addition, it checks harmonics from 0 to 50 and records flicker, which makes it useful for fault finding, routine checks and wider power studies.
The unit also supports a wide clamp range, so you can match it to different current test needs. Used with AmpFLEX or MA193 clamps, the Chauvin Arnoux CA8331 Qualistar+ Power Analyser covers 100 mA to 10,000 A AC for flexible testing on cables and installations.
Designed for everyday use
For day-to-day work, the analyser shows data in graphs and waveforms that are easy to read. It also includes MIN/MAX recording, so you can track the highest and lowest values seen during a test without missing important changes.
A built-in stand supports hands-free use, and USB communication links the instrument to a PC or laptop for reporting. Chauvin Arnoux CA8331 Qualistar+ Power Analyser kits are also supplied with software and a choice of flexible clamps, which helps you get started straight away.
