Extech Battery Coolant/Glycol Refractometer measures the concentration of battery coolant plus battery charge condition. Extech Battery Coolant/Glycol Refractometer is used to check the freeze point of antifreeze used in car and truck radiators. If the antifreeze is diluted, it will freeze if it gets too cold - a very bad thing! This can crack the engine block and destroy the engine.

Anyone who runs a fleet of trucks, buses, cars or even ground equipment - school buses, truck fleets, taxi cabs, the post office, airlines, construction companies, etc - are good prospects for this product.
