This comprehensive voltage, current, and power measuring solution, the Chauvin Arnoux CA8331 Qualistar+ Power Analyser, allows you to do comprehensive diagnostics on even the trickiest electrical systems. The Chauvin Arnoux CA8331 Qualistar+ provides parameter measurement from four voltage channels and three current channels simultaneously (current clamps are needed for current measurements). Its color screen allows you to easily identify power quality loss and ensure energy efficiency by displaying power quality in clear, readable graphs and waveforms. The CA8331 is a handheld portable device with built-in stand for hands-free use. It measures frequency, energy values, harmonics, transients, flicker, and multiple power values. A variety of Chauvin Arnoux clamps are compatible with the CA8331 Qualistar+ Power Analyser; however, for conducting current measurements, the manufacturer suggests using the MN93, MN93A, MA193, PAC93, A193-450, A193-800, C193, and E3N current clamps.
