SBS-6500: Digital Battery Impedance Tester

Digital Battery Analyzer

Complete Battery Impedance Tester and Data Logger (Meets IEEE/NERC Standards)

The SBS-6500 is a multipurpose impedance and voltage tester. Cell and inter-cell and terminal connector readings are taken within seconds using the included pin probes (or optional clamp probes). The SBS-6500 can be programmed with site names, battery details and pass/warning/fail alarm set points for ohmic measurements (pass/fail for voltage) without the high current requirements and float voltage drop necessary for internal resistance testing types. 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 pairs with our SBS-3510, SBS-2510 and SBS-2003 digital hydrometers to import specific gravity readings into the SBS-6500. With this data merge, the SBS-6500 will store and generate reports with voltage, ohmic, temperature and gravity readings.

Data Storage: 300 battery strings x 250 cells per string x 4 tests per year over a period of 25 years = 7.5 million records

The SBS-6500 replaced the discontinued GL-1000, IBEX-1000 and IBEX-Ultra.
