RS PRO Hydrometer

Introducing the excellent-quality and precise battery hydrometer form RS PRO. This glass-made hydrometer is a quality device designed to test the level of charge of a battery cell. It measures a density and specific of electrolyte's gravity. The higher the concentration and density level of sulfuric acid, the higher the state of charge. It also allows each cell to be individually checked at a glance. The high precision scale is in Baume degrees & specific weight with coloured sections for quick reading.
