Vee Gee Battery/Coolant Hand Refractometers

It's essential to know the freezing point of anti-freeze coolants for vehicular safety. Keeping a suitable concentration of coolant prevents engine trouble and possible radiator corrosion. These refractometers (available with either °F or °C ranges) monitor the freezing points of both ethylene glycol and propylene glycol; in addition, they indicate battery recharge level.

Simple to use and virtually an indispensable instrument for gas stations, service shops, cab companies, etc., both refractometer models feature automatic temperature compensation (ATC); an ideal choice for testing in conditions with large ambient temperature fluctuations.
