SBS-3510: Digital Hydrometer and Tester

Digital Battery Hydrometer / Density Meter

Specific Gravity Tester with Downloading Capabilities for Lead Acid or Nickel Cadmium (Ni-Cd) Batteries

The SBS-3510 uses oscillating U-tube technology to measure 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 3.0000. With the ability to communicate wirelessly to a printer or computer via the integrated Bluetooth interface, testing results can be uploaded into an easy-to-read report.

Unlike other digital hydrometers on the market, the measuring cell can be replaced if damage occurs. This design feature eliminates the need to replace the entire unit should the measuring cell become damaged.

An optional 90 degree bent filling tube provides easier access for measuring specific gravity in battery cells that are located in tight and hard-to-reach areas.

Maintaining the digital hydrometer through proper maintenance is essential to long lasting service life and accuracy. Exponential Power recommends a maintenance interval of at least once a year. Exponential Power is able to meet all digital service needs.

Features Measures specific gravity, ambient temperature and count Tests both lead acid and nickel cadmium batteries Time savings: 5 times faster than conventional methods ± 0.001 accuracy Automatic temperature compensation Compact, lightweight design enabling one-hand measurement Stores up to 100 sample IDs for easy sample identification Stores up to 1024 measurements including time stamps and sample IDs Bluetooth interface for data exchange Ability to connect with the SBS-6500 impedance tester via Bluetooth for integrated data and reporting LCD display Available: Complete Battery Testing Package Combine the SBS-3510 digital hydrometer with the SBS-6500 impedance tester for an all-in-one solution for your battery testing needs. This combination is a popular option for vented lead-acid applications and companies with NERC requirements and IEEE standards.
