Function 1: Measuring freezing point temperture of ethylene glycol or propylene glycol based automobile antifreeze coolant. Scale range: ethylene glycol base: -84°F-32°F, propylene glycol based -60°F-32°F
Function 2: Measuring concentration of ethylene glycol or propylene glycol based automobile antifreeze coolant. Scale Range: ethylene glycol base: 0-70% propylene glycol based 0-63%
Function 3:Measuring specific gravity of battery acid and provide a quick reference of battery charge condition. Scale Range:1.100~1.400kg/l
Features automatic temperature compensation: makes it more convenient to use in different temperature.
Quick and easy: Just need 2-3 drops of solution and a few seconds, you can get accurate readings. And no battery needed.
