AUTOUTLET Fahrenheit Antifreeze Refractometer with ATC Function for Checking Freezing Point of Automobile Antifreeze Systems,Battery Fluid Condition,Battery Acid, Glycol, Coolant, Antifreeze Tester

* Widely Measuring: This Antifreeze Refractometer Tester is a portable tool for car owners. It can be used to test freezing point of automobile antifreeze systems,battery fluid condition,battery acid, glycol, coolant. * ATC Function: The Antifreeze Refractometer is with automatic temperature compensation function.It is more convenient to use at different temperatures. * Easy to Check Reading: Just need 2-3 drops of solution and wait for a few seconds, then you can get accurate data.And no battery needed. * Ethylene Glycol or Propylene Glycol Measuring Rage: Measuring freezing point of automobile antifreeze based on ethylene glycol or propylene glycol. Scale Range: ethylene glycol based: 32 to -84 degree F, propylene glycol based:32 to -60 degree F. * Battery Acid Measuring Range: Measuring specific gravity of battery acid and provide a quick reference of battery charge condition. Scale Range:1.100~1.400kg.
