Carry out power diagnostics on even the most complex electrical systems with the Chauvin Arnoux CA8331 Qualistar +, a comprehensive solution for measuring voltage, current and power.
Featuring the ability to measure parameters from four voltage channels and three current channels simultaneously (current clamps required for current measurements), the CA8331 clearly breaks down power quality into easy-to-read graphs and waveforms, allowing professionals to easily determine where power quality is being lost and take corrective action to ensure energy efficiency.
Designed for use out in the field, and comfortable to hold in the hands, or suitable for hands-free use thanks to a built-in stand, the CA8331 evaluates the following aspects of power quality: frequency, multiple power values, energy values, harmonics and flicker.
Chauvin Arnoux recommends using their MN93, MN93A, MA193, PAC93, A196-450, A193-450, A193-800, C193 and E3N current clamps with this instrument to carry out current measurements.
