GW Instek GPM-8320 (GPIB+DA12) Digital AC Power Meter

Overview

The GW Instek GPM-8320 (GPIB+DA12) is a 2-channel digital power meter designed for precise AC power measurement in single-phase and three-phase systems. With a 5-inch TFT LCD display and 16-bit A/D converters, it provides simultaneous measurements of voltage, current, power, and harmonic content. The integrated GPIB and digital I/O interfaces enable automated test sequences and data logging in laboratory and production environments.
