Chauvin Arnoux CA8331 Qualistar+ Power Quality Analyser
Chauvin Arnoux CA8331 Qualistar+ Power Quality Analyser gives test and maintenance teams a clear view of electrical network quality. It measures many key values at the same time, so users can check system condition faster and with less setup.
Its compact body makes field work easier, while the large number of measured values adds strong practical use. In addition, the unit supports three voltage channels and three current channels, and it can detect connected current sensors automatically.
Built for detailed power checks
Users can measure TRMS AC+DC voltage and current, frequency, power values and energy values in one instrument. As a result, Chauvin Arnoux CA8331 helps users review load behaviour, follow energy use and spot power quality issues without carrying extra equipment.
Harmonic analysis is also included, with phase and orders from 0 to the 50th. Furthermore, the analyser supports flicker measurement, peak detection and vectorial representation, which helps users study network behaviour in more depth.
Made for site work and long logging runs
For work on site, Chauvin Arnoux CA8331 combines a colour 1/4 VGA TFT screen with USB communication and a strong IP53 IK08 housing. It also runs on a 9.6 V NiMH rechargeable battery or mains power supply, so it suits both mobile checks and bench work.
Data recording is a strong point of this model because it can record a selection of parameters at the maximum sampling rate for periods from 4 hours to 2 weeks. Chauvin Arnoux CA8331 also offers MIN/MAX recording, unbalance checks and up to 12 screen and curve captures, which supports clear reporting after the job is done.
