The GBM-3100H is an expansion model of the existing GBM-3000 series, providing measurement capabilities up to 1000V DC voltage which is suitable for measurement of EV and PHEV battery packs. This expanded model is equipped with a 3.5-inch color display and has high measurement accuracy (0.01%) for battery voltage and (0.5%) for internal resistance of battery.

The GBM-3000 series, which uses AC 1kHz as the test signal and measures battery’s voltage and internal resistance to 1000V (GBM-3100H), 300V (GBM-3300) and 80V (GBM-3080).
