Disc-type anti-freeze tester with rubber suction bulb and floating coloured discs to easily check freeze protection levels in ethylene glycol coolant.
This anti-freeze tester is a simple and practical tool for checking the freeze protection level of ethylene glycol coolant in vehicle cooling systems. A rubber suction bulb draws a sample into the clear chamber, where six floating coloured indicator discs rise according to coolant strength. An easy-to-read temperature table helps interpret results, showing approximate protection from mild to severe cold conditions. Compact and lightweight, it’s ideal for routine garage or workshop coolant checks.
