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 G ml for accurate readings. The colour-coded scale simplifies interpretation: red 1.100-1.205 G ml indicates a discharged battery, white 1.205-1.260 G ml shows the battery requires attention, and green 1.260-1.300 G ml 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. Features and benefits: checks the charge of a battery by measuring the density of the electrolyte in the cells colour-coded graduations provide instant visual indication of battery condition precision 0.005 G ml graduations for accurate diagnostic readings contents: 1 x battery hydrometer
