This automotive coolant refractometer is designed to test concentration of

antifreeze liquid, cleaning fluids, electrolyte solution batteries strength in

unit of Specific Gravity (sg) and measures the concentration of battery coolant

plus battery charge condition. With the indication of the percentage of

concentration, you will know at which temperature (centigrade ) of the fluid

will be frozen for both Propylene Glycol and Ethylene Glycol. It checks the

freezing 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. The built-in ATC is automatically

adjusted to correct temperature discrepancies of environment temperature. It

uses ambient light only and no batteries are needed.
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, car and truck radiators, large commercial air conditioners, etc - are

good prospects for this product. It insure that all is working properly, and not

causing problems (like rust, prone to freezing, poor charging, poor cooling,

etc.). This unit is also fantastic for testing aviation grade hydraulic oils

(like Skydrol), Glycol-based heat transfer fluids, and fire resistant hydraulic

fluids used in die casting or foundry applications.
