Which analyses are included in an extended coolant analysis?
A short explanation of the extended coolant analysis package
An extended analysis includes ICP/elemental analysis, pH, nitrite, sulphate, reserve alkalinity, chlorides, calculated freezing point, hardness, oil test yes/no and Brix %.
The analysis package will typically be able to detect whether contaminants are present, such as seawater, exhaust gases, oil, or wear and corrosion metals
Note: In order to know what is contamination it is important to also test new, unused fluid for comparison
