GBM-3300 | Battery tester (battery meter), 300 V AC-IR and DC

The GBM-3300 battery tester from GW Instek offers flexible measurement functions for determining the battery voltage and internal resistance in a particularly handy format. The clear display enables a quick interpretation of the measurement results so that the battery tests can be optimally integrated into your work processes. With a basic accuracy of 0.01% for voltage measurements and 0.5% for resistance measurements, the battery tester meets the high test requirements in development and production. Integrated statistical functions provide you with the key figures such as Mean, Min, Max, Cp, CpK etc. in real time so that you can evaluate the status of your production at any time. For further data processing, up to 10,000 measured values can be saved on the internal device memory and then transferred to a computer via USB stick. So the battery tester can be used mobile and PC-independent where it is needed.

Simplify your workflow when evaluating batteries - from the individual cell to the finished product.

  • Two display options on the display: "Simple Mode" for quick measurement results during production due to optimal readability, "Standard Mode" for additional control of the measurement parameters in development and technical validation
  • Integrated statistical functions provide essential key figures for statistical evaluation of your current production process
  • Pass / Fail assessment: individual HI / LO settings depending on the measurement requirements for an objective assessment of the measurement results
  • High-resolution display of the measured values: 6-digit voltage values and 5-digit resistance values for precise measurement results
