Description in English:

The Qualistar+ C.A 8331 is a powerful power quality analyzer designed for maintenance and testing in industrial and commercial installations. With its 4 voltage inputs and 3 current inputs, it enables precise measurement of all voltage, current, and power parameters of a network. The device offers simultaneous recording of all power quality parameters and provides an immediate overview of critical values such as harmonics, flicker, and peak levels.

Its compact and robust design, combined with a large, easy-to-read TFT color screen, makes the C.A 8331 ideal for field use. Color-coded inputs simplify handling, while automatic recognition of connected current transformers ensures intuitive operation. The included Power Analyser Transfer software allows for easy data retrieval, analysis, and export to Excel. With a battery life of up to 13 hours, the Qualistar+ is well-suited for extended use.
