The Express Inhibitor Test provides a rapid on-site analysis of the concentration of all Fernox Protectors, and other molybdate based inhibitors, in central heating system water. Easy and intuitive to use, it is a quick and simple testing method to establish the presence of inhibitor within the system. Testing the concentration of inhibitor may be required for compliance with boiler warranties.
When used in conjunction with the Fernox Water Test App, which is free to download from the Apple App Store or Google Play Store, this single usage, on-site heating system test can be saved within the App and a lab-style report certificate is available to download. A pass or a fail is confirmed based on the colour of the test strips compared against the colour chart on the pot. In the event of fail result, corrective action can be take immediately by simply adding more inhibitor and retesting to receive the pass certificate – saves time as there is no need for return visits to site.
