High Performance Battery Quality Analyzer

Data Logger with Trend Analysis

Abundant Data Logging and Accurate Trend Analysis is available backed by Internal SD Card stored up to 7.5 million data in Text or Graphic mode

  • The Battery Quality Analyzer is designed for measuring the internal resistance, opencircuit voltage, and terminal temperature of secondary batteries, including Lead Storage Cells (Lead -Acid batteries), nickel-cadmium batteries, lithium-ion batteries and nickel-metal hydride batteries.
  • AC four-terminal method to measure the internal resistance by eliminating lead resistance and contact resistance to get the accurate results.
  • Multiple display to show the internal resistance, voltage and temperature or voltage, current and temperature of the battery simultaneously.
  • It has 99 sets of composite comparator function, which can be set at resistance and voltage values to get the reliable detection of battery deterioration.
  • Pin type lead, which can easily contact the battery electrodes supplied as standard to get more accurate 4-terminal measurement.
  • Clamp adaptor for DC current or AC current measurements.
