- Antifreeze Tester test at hot & cold temperatures.
- Six floating discs for accurate reading.
- Indicator range from -7 to -37 degrees Celsius / from +25 to -34 degrees Fahrenheit.
- Pure antifreeze will freeze at -12°C /10.4°F.
- It permits to determine, with good approximation, the freezing point of the anti-freeze/coolant in the radiator and to reset the required protection level.
Antifreeze Tester (AT-906) is designed for any Ethylene Glycol (EG) based antifreeze or coolant solution. This tester is composed of a transparent graded tube with six discs inside, a black rubber pipe, and a black rubber pump.
Using AT-906 can check the protection level of your antifreeze or coolant solution precisely and also can assist you to make the ideal antifreeze or coolant solution to match what you need; moreover, it can be read both in Celsius and Fahrenheit, for whether the testing condition is hot or cold, it can still perform well and accurately!
How to use Antifreeze Tester :
Use the pump to suck a portion of antifreeze solution into the tester and control the graded tube when the floats stop.
The number of floating discs shows the level of protection. (Please refer to the table below)

If six discs are all floated, this condition means not safe anymore (with no protection), and if the protection level is not sufficient enough, please adjust the mixing ratio of water and ethylene glycol.
After the testing, please clean and dry the tester for next use.
