Digital hydrometer allows a quick and easy determination of specific gravity of sulfuric acid in batteries. Specific gravity measurements best identify failing battery cells compared to voltage testing, which only shows the float charge. The digital hydrometer also displays either concentration of ethylene glycol (%), freezing temp of ethylene glycol (°C), or temp of sample cell (°C). For measuring concentration of antifreeze solution used for central heating system...as a part of equipment, solution control.

Ideal for measuring the condition of antifreeze solution for vehicle radiators. Perfect for measuring specific gravity of battery fluid (dilute sulfuric acid) in utility, telecommunication and switch gear stationary battery testing. Specific Gravity: Accuracy of ±0.005 units-500% faster than conventional sightglass methods. Battery fluid samples pumped through the digital hydrometer sample hose and nozzle to sample chamber where measurements are taken. Gasket ensures a liquid-tight seal
