Draper Anti-Freeze Tester Disc 35807

This disc-type antifreeze tester measures the density of ethylene glycol-based antifreeze to determine coolant strength. It uses six floating discs to indicate concentration, providing readings in both Celsius and Fahrenheit. The device is suitable for testing both hot and cold coolant in automotive and industrial cooling systems, enabling quick and accurate assessments without the need for additional accessories for basic testing.

Features

• Six floating discs for precise density readings
• Celsius and Fahrenheit readings
• Range: -7 to -37 °C (25 to -34 °F)
• Hot or cold coolant testing
• No extra accessories needed for basic testing

How to use

1. Immerse the tester into the coolant sample at the desired temperature.
2. Observe the position of the floating discs to read the antifreeze concentration.
3. Read the antifreeze concentration in the appropriate temperature unit.
