GW Instek GBM-3300 300V Battery Meter

Overview

The GW Instek GBM-3300 is a 300V desktop battery tester from the GBM-3000 series, designed for measuring battery voltage and internal resistance with AC 1kHz test signal. The meter features a 3.5" TFT LCD display, 4-wire measurement method with high resolution (6-digit voltage / 5-digit resistance display), and is suitable for testing battery cells, battery packs, and complete battery assemblies throughout the production process.

The GBM-3300 provides excellent measurement accuracy for open circuit voltage and resistance analysis at 300V ranges. With voltage accuracy of ±(0.01% reading + 3 digits) and resolution up to 10 µV, combined with resistance accuracy of ±(0.5% reading + 5 digits) and 0.1 µΩ resolution, it is ideal for mid-range battery systems and quality assurance applications.
