Draper Anti-Freeze Tester

The Draper Anti-Freeze Tester is a precision diagnostic tool designed for testing the frost protection levels of methanol and ethylene glycol antifreeze in vehicle cooling systems. This essential workshop tool measures the density of the water-antifreeze mixture to verify adequate frost protection, helping prevent costly engine damage during cold weather. Manufactured with a glass tube body, PVC bulb and spout, this tester features dual green and white scales for accurate readings in different conditions. The green scale should be used when the engine is hot, whilst the white scale is designed for cold engine testing. The testing range covers methanol from -40°C to -12°C and ethylene glycol from -34°C to -12°C, providing comprehensive coverage for common antifreeze types. Ideal for automotive workshops, mobile mechanics and vehicle maintenance professionals, this tester offers a straightforward method to check cooling system protection. The simple draw-and-read operation allows quick assessment of antifreeze concentration, ensuring customers' vehicles are properly prepared for winter conditions.
