Digital Battery Hydrometer / Density Meter

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

Whether in a telecommunications central office, utility substation or critical data power battery room, the ability to spot-check the specific gravity of suspect cells is invaluable. Performing your own preventative maintenance on your flooded batteries is greatly simplified when employing this digital hydrometer.

The SBS-2500 offers the ability to test the 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 2.0000.

The hydrometer’s internal memory will store up to 1100 individual specific gravity and temperature readings. Readings can be uploaded into an easy-to-read report using the included software.
