Sealey Propylene Glycol Antifreeze Disc Tester

The Sealey Propylene Glycol Antifreeze Disc Tester is a specialist diagnostic tool designed for testing modern propylene glycol-based coolant systems. This lightweight tester provides quick and accurate assessment of antifreeze protection levels in both hot and cold engine conditions, making it an essential tool for workshops, mobile mechanics and vehicle maintenance professionals. The disc flotation system offers a straightforward visual indication of coolant protection levels. When a coolant sample is drawn into the tester, the number of large coloured discs that float directly corresponds to the level of freeze protection, with results referenced against the easy-to-read temperature table printed on the body. This eliminates guesswork and provides reliable diagnostic information for coolant system maintenance. Built from tough, virtually unbreakable plastic, this compact tester is engineered to withstand the demands of professional workshop environments. The durable construction ensures long-term reliability, whilst the clear markings remain legible throughout the tool's service life. Ideal for garages, fleet maintenance operations and mobile repair services working with propylene glycol coolant systems.
