Battery hydrometer for measuring the specific gravity of lead-acid battery electrolyte to assess state of charge and health.
This battery hydrometer is a simple and effective diagnostic tool for checking the specific gravity of electrolyte in lead-acid batteries. By drawing a sample into the hydrometer, the internal float will rise or fall with the density of the liquid, giving a clear indication of the battery’s charge level and condition. It’s ideal for routine maintenance on automotive, marine or industrial batteries and helps identify weak cells before they fail.
