SBS-2003: Digital Hydrometer and Tester

Digital Battery Analyzer / Density Meter

Specific Gravity Tester for Lead-Acid Batteries

Specific gravity testing is easy and efficient with the SBS-2003. Simply insert the nozzle into the battery and depress the finger pump, which draws a few drops of sulfuric acid (H2SO4) through the tube. Within three seconds the measured refractive index is converted into a temperature compensated specific gravity reading and the specific gravity, temperature and cell count are displayed. After testing is completed, you can transfer the data to your computer via Bluetooth and download results into an Excel report.

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 with lead acid batteries.

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

The SBS-2003 replaced the discontinued SBS-2002.



  • Measures specific gravity, ambient temperature and count within 3 seconds
  • Automatic temperature compensation to 77° F (or 25° C)
  • Time savings: 5 times faster than conventional methods
  • Stores up to 1000 readings
  • Wirelessly transfers testing data via Bluetooth to provided software to create an Excel report


  • Able to record temperature in Fahrenheit or Celsius
  • ± 0.002 accuracy
  • LCD display
  • IP64 water resistant

Example of Cost Savings

Exponential Power 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.

Available: Complete Battery Testing Package

When the SBS-2003 Digital Hydrometer is combined with our SBS-6500 battery diagnostic impedance tester, it becomes an all-in-one solution for your battery testing needs. This package is popular with vented lead acid clients and companies with NERC requirements or IEEE standards.
