sell Antifreeze Refractometer

The models have only one unit system: °C. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. And they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze liquids. The RHAN-200ATC has Automatic Temperature Compensation System. Measuring Range: Ethylene Glycol: -60°C-0°C 0--66.6% Propylene Glycol: -50°C-0°C 0--62.4% Battery Fluids:1.100-1.400sgResolution Factor:5°C, 5°C, 0.01sg (ATC)Temperature Compensation Range:10°C--30°C
