Antifreeze Refractometer, Hand Coolant Tester for Ethylene Glycol, Propylene Freezing Point of Windscreen Water AdBlue Battery Acid, Urea Concentration

This style is equipped with °C. By specifying the percentage, we can 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. Use: this refractometer can be used to determine the ethylene glycol and propylene glycol concentration of the antifreeze of your car, solar system, heat pumps, the freezing point of windscreen washer water, heating system or other machines or systems. High quality: our chrome plated brass body is resistant to chemical corrosion and wear resistant, the service life of the refractometer is increased several times than other aluminum housings.
