Draper Battery Hydrometer

The Draper Battery Hydrometer is a precision instrument designed for testing the specific gravity of electrolyte solution in individual battery cells. This battery fluid tester features a colour coded graduated scale to provide clear visual indication of battery charge status, making it an essential diagnostic tool for automotive technicians, mechanics and maintenance professionals working with lead acid batteries. Manufactured with a durable glass tube, PVC bulb and spout, this hydrometer measures electrolyte density with graduations of 0.005 gml for accurate readings. The colour coded scale simplifies interpretation red 1.100 1.205 gml indicates a discharged battery, white 1.205 1.260 gml shows the battery requires attention, and green 1.260 1.300 gml confirms a fully charged state. Calibration should be carried out at 20°C for optimal accuracy. Ideal for workshop diagnostics, fleet maintenance and battery testing applications, this hydrometer allows technicians to assess individual cell condition and identify failing cells in multi cell batteries. Care must always be taken when removing battery cell caps and when testing to ensure safe operation.
