Hand held Glycol Antifreeze coolant Battery Refractometer
Antifreeze Refractometer can be used to test the concentration of ethylene glycol or propylene glycol in antifreeze liquids.
Antifreeze Refractometer have only one unit system: °F. 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 RHA-503ATC has Automatic Temperature Compensation System.
