SBS-3500 Hydrometer

Digital Battery Hydrometer / Density Meter

Specific Gravity Tester with Downloading Capabilities
for NiCd & Lead Acid Batteries

The SBS-3500 uses oscillating U-tube technology to measure specific gravity and temperature of lead acid or nickel cadmium batteries within seconds. The unit is able to take readings between the range of 0.0000 to 3.0000. With the ability to communicate wirelessly to a printer or computer via the integrated IrDA interface, testing results can be uploaded into an easy-to-read report.
