GW Instek GPM-8330 3-Channel Digital Power Meter

Overview

The GW Instek GPM-8330 is a 3-channel digital power meter specifically designed for three-phase AC power measurement. Supporting up to 1000V AC input and multiple wiring configurations (1P3W, 3P3W, 3P4W, 3V3A), it measures comprehensive power parameters with 0.1% reading accuracy. The 5-inch TFT LCD display shows real-time waveforms and 25 different power measurement parameters, making it ideal for electrical equipment testing, power quality analysis, and efficiency calculations.
