The Acustrip 3300 Series of Cool Check® Coolant Quality Test Strips is the superior way to protect your engine investment. When poor quality make-up water is added to the system or when minimum coolant maintenance is not observed, pH levels can rise or fall to dangerous levels and contaminants (Sulfate and Chloride) can rise to unacceptable levels. The effect of a blown head gasket can also be detected as the exhaust raises the level of Sulfate and reduces the pH. The Cool Check® strips detect these issues by determining the level of pH, Sulfate and Chloride on Site, in a matter of minutes. The specific ranges are as follows:
- Chloride 0 - 400 ppm
- Sulfate 0 - 3000 ppm
- pH 6 - 11
