SBS-2002 Hydrometer

Digital Battery Hydrometer / Density Meter

Specific Gravity Tester for Lead-Acid Batteries 


The SBS-2002 is lightweight, durable and easy to use, making it suitable for use in all industrial environments. Simply insert the nozzle into the battery and depress the finger pump which draws a few drops of sulfuric acid (H2S04) through the tube. Within three seconds the measured refractive index is converted into a temperature-compensated specific gravity reading and then both the specific gravity and temperature are displayed.

How the Digital Hydrometer Operates

how SBS digital hydrometer operates



Example of Cost Savings

Field studies show time savings of at least 5 times (500%) using a digital hydrometer over a standard glass hydrometer and thermometer.


If you spend 60 minutes testing specific gravities every month in 20 sites, this total, 60 minutes x 20 sites x 12 months per year = 14,400 minutes divided by 60 minutes = 240 labor hours per year.


Since we can reduce this time by 500%, 240 hours divided by 5 = 48 hours total time with the SBS-2002.


That’s a savings of 192 hours per year. Multiplied by $45.00 per hour labor cost with benefits: 192 x $45.00 = $8,640.00 of savings per year.
