SBS-3500: Digital Hydrometer and Tester

Digital Battery Hydrometer / Density Meter

Specific Gravity Tester with Downloading Capabilities for Lead Acid or Nickel Cadmium (NiCd) Batteries

The SBS-3500 uses oscillating U-tube technology to measure specific gravity and temperature of lead acid or nickel cadmium (NiCd) batteries within seconds. The unit offers a wide reading range, 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.
