Exponential Power introduced the first digital battery hydrometer to the U.S. stationary battery market in 1988. For over 30 years, Exponential Power has sold and serviced thousands of hydrometers and continues to provide the newest technologies in battery maintenance equipment today.
Hydrometers (density meters) measure the specific gravity of a battery’s electrolyte. Based on the specific gravity, the user can determine the state of charge of the battery. Retaining these hydrometer readings and data over time is recommended by IEEE as part of any Battery Maintenance Program.
Digital hydrometers are commonly used in utilities, telecommunications, industrial, food and beverage, petrochemical and other applications.
In contrast to the old bulb-style hydrometers of the past, our digital hydrometers provide accurate recording, storage and transfer of battery data to a PC -- eliminating hours of hand recording and entering data. As a result, time spent on battery maintenance is reduced significantly.
