4 in 1 Automotive Antifreeze Refractometer Car Urea Fluid Tester Battery Freezing ATC Detector Handheld Electrolyte Hydrometer

[xlmodel]-[custom]-[8888] Multi-functional freezing test The handheld refractometer is a small precision optical instrument that measures the concentration and freezing point of the solution. It is the basic principle that the refractive index of the solution is measured using the total reflection critical angle, and then the concentration, freezing point and performance of the measured solution are determined. Main Uses: Measurement of freezing point of antifreeze, proportion of electrolytes of leadacid batteries and glass water freezing point The main technical temperature supplement type, with a temperature compensation device to ensure normal measurement at 10 ~ 30 CRange of measurements Minimum Scale Size net weight Range of measurements Minimum ScaleAn
