The Storage Battery Systems SBS-6500 Digital Battery Resistance Tester measures the impedance (internal resistance), voltage and temperature of batteries across all applications and types including lead acid cells, nickel-cadmium batteries, lithium-ion batteries and nickel-metal hydride batteries. Readings of cells and intercell connectors are taken within seconds using the included pin probes (or optional clamp probes). This model meets IEEE and NERC maintenance recommendations for stationary battery systems. The SBS-6500 can be programmed with site names, battery details and pass/warning/fail alarm set points for resistance measurements (pass/fail for voltage). All data is retained in the meter's internal memory for easy on-site access. With a computer and the included software, the SBS-6500 generates custom graphical reports for historical trending and comparisons. The SBS-6500 can also be paired with the SBS-2003 digital hydrometer to import specific gravity readings from the SBS-2003 into the SBS-6500. With this data merge, the SBS-6500 will store and generate reports with voltage, resistance, temperature and gravity readings.
