• This tool is used to test the battery charge state
• Easy test result reading thanks to the clear colour coded scale
• It determines the charge state by measuring the specific gravity (density) of the electrolyte
• The greater the concentration of sulphuric acid, the more dense the electrolyte becomes. The higher the density, the higher charge
• Tube material glass
• Clean with water after each use and dry before next use
• Packed in a white cardboard box
