SBS-3500 Hydrometer

Digital Battery Hydrometer / Density Meter  

Specific Gravity Tester with Downloading Capabilities
for Ni-Cad & Lead Acid Batteries


The SBS-3500 is a portable specific gravity meter that uses oscillating U-tube technology to measure the density of your sample, supplying results within seconds. With the ability to communicate wirelessly to a printer or PC via the integrated IrDA interface, it allows you to upload specific gravity test results to the included software.


This is a great solution for battery systems, general industrial, and laboratory applications.
