SKU : HEG93 Ethylene Glycol Coolant Hydrometer (Tester )

Hydrometer c\w unabreakable transparent perspex tube

Easy to read indicator and designed for modern Ethylene Glycol antifreeze
Number of floating discs indicates level of antifreeze protection.
Tests at hot and cold temperatures and reads in Celsius and Fahrenheit.
Floating orange disc shows over protection and loss of efficiency.
50/50 mixture - the coolant will boil at 107 deg C (228deg F) and freeze at -37deg C (-34deg F)
70/30 mixture - the coolant will boil at 135 deg C (276deg F) and freeze at -64deg C (-84deg F)
Solution with more than 70% antifreeze will give less protection.
Pure antifreeze will freeze at -21C (-6 F)

Note! Distilled or deionized water should be used for Ethylene glycol solutions.

City water is often treated with chlorine, which is corrosive, and should be avoided.
One of the best method to determine if the coolant is properly mixed is to measure the strength or concentration of the antifreeze with a hydrometer.
After checking then you can safely decide to add more antifreeze or distilled water
