Draper Disc Type AntiFreeze Tester

The Draper Disc Type AntiFreeze Tester is a professional coolant testing instrument designed for measuring propylene glycol antifreeze density and concentration. Using a five-disc floating system, this tester provides accurate temperature readings in both metric and imperial units, making it an essential tool for automotive technicians and vehicle maintenance professionals who need to verify coolant protection levels.

The disc-based testing method allows for precise assessment of coolant condition and freeze protection capability across a wide temperature range. This tester is suitable for checking both hot and cold coolant systems, providing flexibility during service intervals and emergency diagnostics without waiting for engine cooling.

Ideal for workshop environments, mobile mechanics, and fleet maintenance operations, this antifreeze tester helps ensure cooling systems maintain adequate protection against freezing and corrosion. The straightforward disc reading system eliminates the need for complex interpretation, delivering clear results that inform decisions about coolant replacement or top-up requirements.

Features and Benefits:
• For testing propylene glycol coolant density
• Measuring range from -7 to -46°C / +20 to -50°F
• Suitable for testing both hot and cold coolant strengths
• Five floating discs enable accurate readings in both Celsius and Fahrenheit
