Hydrometer Digital Hydrometers have been developed to take readings up to 5 times faster than the old bulb style manual float hydrometers used in the past tomeasure specific gravity of battery cells. With automatic temperature compensation and data storage and transfer, importing raw data into maintenance records is now easier than ever. These highly accurate Hydrometers measure the Specific Gravity of battery cells and provide the best indication of state of charge.
Durable in construction, ease of operation, simple controls and one button push to test features simplify this task to a few seconds per cell versus manual method of obtaining these readings in the past.
