Overview
The 4-in-1 Coolant Refractometer is a versatile and precise tool designed for automotive maintenance, capable of measuring the freezing point of antifreeze (both ethylene and propylene glycol), the concentration of Diesel Exhaust Fluid (DEF/AdBlue), the specific gravity of battery acid, and the freezing point of windshield washer fluid. It features automatic temperature compensation (ATC) to ensure accurate readings across a wide temperature range without manual adjustments. Built with a durable copper alloy body with chrome plating, the refractometer offers long-lasting performance and resistance to wear. Its user-friendly design includes an adjustable manual focus and a comfortable rubber eyepiece for easy viewing. Compact and lightweight, it is highly portable and comes complete with a calibration screwdriver, transfer pipette, and storage case, making it an essential tool for both professional technicians and DIY enthusiasts to maintain optimal vehicle fluid performance and safety.
