    • Description
    • Additional information
    • Delivery

    Fernox LP Sterox Test Strips provide a simple and reliable way to measure Sterox biocide levels in domestic water systems. They help installers and facilities managers confirm correct dosing during legionella treatment. As a result, users can maintain effective water hygiene control with confidence.

    Accurate testing plays a key role in legionella risk management. Therefore, Fernox  Test Strips support compliance while reducing guesswork during system treatment.

    What Are Fernox LP Sterox Test Strips?

    LP Sterox Test Strips are single-use strips designed to measure the concentration of LP Sterox biocide in water. Each strip reacts instantly when dipped into treated water, producing a clear colour change.

    Users can compare the colour result against the reference chart. Consequently, they can quickly confirm whether biocide levels fall within the recommended range.

    How Fernox LP Sterox Test Strips Work

    To test the system, users dip a strip into the water sample for the specified time. The reactive pad responds to the presence of  Sterox biocide. Therefore, the strip displays a visible colour change.

    Because the process takes only seconds, users can carry out testing during commissioning, routine checks, or follow-up inspections.

    Accurate Biocide Level Measurement

    Fernox LP Sterox Test Strips provide clear and repeatable results. As a result, users can confirm correct dosing and adjust treatment if required.

    Fast and Simple Testing

    The strips require no specialist equipment or training. Therefore, installers can perform on-site testing quickly and efficiently.

    Supports Legionella Risk Management

    Regular testing helps ensure ongoing water hygiene control. Consequently, Fernox LP Sterox Test Strips support effective legionella risk management strategies.
