This BRAND NEW hand held coolant detecor refractometer is kind of portable precision optical instrument made according to the light refraction principle. It is used to simly measure the density and freezing point to ethylene and ethanediol in antifreezing fluid or coolant. This coolant detector is equipped with the auotmatic temperature compensation (ATC) system inside, which can reduce the frequency of zeroing. ATC range: 10 C degree--30 C degree. It is made by Metal, no cheap plastic.
