SBS-2003 Digital Battery Hydrometer and Tester

Digital Battery Hydrometer / Density Meter 

Specific Gravity Tester for Lead-Acid Batteries


Specific gravity testing has never been this easy. No more need to write down hundreds of readings and type them into reports or spreadsheets once you are off of the job site.


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 the specific gravity, temperature and cell count are displayed. You can transfer the data to your PC or laptop via Bluetooth and download results into Excel.


Combining a light-weight and durable design with easy maintenance, field-replaceable spare parts and a large data storage memory, the SBS-2003 is suitable for use in all industrial environments, from Data Centers to Utility Substations.


The SBS-2003 has the added benefit of storing the results for future download via Bluetooth.


hydrometer transfers battery specific gravity data to Excel via Bluetooth



















  • Via Bluetooth, wirelessly transfers testing data to supplied Excel template
  • Time savings — 5 times faster than conventional methods
  • Measures specific gravity, ambient temperature and count
  • Automatically temperature compensates to 77º ˚F (or 25º C)
  • Stores up to 1000 readings — can export raw data to Excel from template




  • Exclusive to Storage Battery Systems LLC (SBS Battery)
  • ±0.002 accuracy
  • LED display
  • IP64 water resistant
  • Field calibrate with distilled water
  • Hydrometer for lead-acid batteries only




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-2003.


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.


time savings by using digital hydrometer vs. manual hydrometer

















The new SBS-2003 hydrometer is compatible with MS Windows and Office.
