What Are Fernox Inhibitor Test Strips?
Fernox Inhibitor Test Strips are easy-to-use diagnostic strips designed to detect Fernox inhibitor presence in heating system water. They provide clear visual results within seconds. Consequently, installers can quickly confirm whether inhibitor levels remain effective.
Because the strips require no specialist tools, they suit both professional engineers and routine maintenance checks.
Why Testing Inhibitor Levels Matters
Over time, inhibitor concentration can reduce due to leaks, refilling, or system maintenance. When protection drops, corrosion risk increases. As a result, sludge formation and component damage become more likely.
By testing inhibitor levels regularly, installers ensure systems stay protected. Furthermore, early detection prevents costly repairs and performance loss.
How Inhibitor Test Strips Work
To use the strips, installers simply dip one into a heating system water sample. The strip reacts immediately and displays a colour change. Therefore, results appear quickly and clearly.
The colour result indicates whether inhibitor levels meet recommended protection standards. Consequently, engineers know when to top up inhibitor levels.
Key Features of Fernox Inhibitor Test Strips
Inhibitor Test Strips deliver fast, accurate results. They provide a simple visual indicator that reduces guesswork. As a result, system protection checks become faster and more reliable.
The compact format makes them easy to carry in tool kits. In addition, they support repeat testing during servicing visits.
Applications and Suitable Uses
Routine Heating System Servicing
During annual servicing, Fernox Inhibitor Test Strips confirm whether protection remains effective. Therefore, engineers can recommend inhibitor top-ups only when required.
System Commissioning and Maintenance
After inhibitor dosing, the strips verify correct concentration levels. As a result, installers complete commissioning with confidence.
Benefits for Installers and Homeowners
Fernox Inhibitor Test Strips help installers deliver better service quality. They reduce uncertainty and support professional system assessments. Consequently, customer trust improves.
Homeowners benefit from continued corrosion protection and improved heating efficiency. Furthermore, regular testing extends system lifespan.
