aichose 3-in-1 Antifreeze Tester in Fahrenheit Scale for Checking Freezing Point and Concentration of Ethylene Glycol or Propylene

This optical refractometer with six scales is designed to measure coolants and antifreeze based on ethylene glycol or propylene glycol, and measure battery fluid condition (density of the electrolyte and each scale division corresponds to 0.01g/cm3). It also measures screenwash antifreeze (windshield washer fluid) based on ethanol as well as on isopropyl alcohol. And check the urea concentration in AdBlue.
