Follow the method
Use the supplied instructions, sample carefully and read the result within the stated conditions and timing.
Water-treatment checks
How do I know if my heating inhibitor is working?
An inhibitor test can indicate whether the sampled water appears to fall within the test method’s stated range. It cannot prove that every component is protected or identify every corrosion risk.
Interpret the result in context
Consider the system
Recent filling, leakage, dilution, repairs and different treatment products may affect interpretation.
Check related evidence
Review turbidity and pH information, system history and product or manufacturer guidance before deciding what happens next.
A result is not a prescription
Do not add inhibitor or another chemical solely because of a website result. A recorded range does not certify complete protection, system safety or compliance.
