    Chemicals High Tolerance Two-Electrode System Hydrogen Peroxide Sensor For All Water Treatment


    The two-electrode system membrane hydrogen peroxide sensor WP10 has the following features and advantages, making it an excellent performer in the field of water treatment:


    Features


    Mechanically strong membrane system

    The sensor adopts a high-strength membrane system design, which can operate stably in harsh environments and effectively prevent damage.


    Surfactant tolerance

    It has high tolerance to surfactants (such as detergents or chemical reagents) and is suitable for a variety of water quality conditions.


    High tolerance to chemicals

    It can resist the influence of a variety of chemicals (including strong oxidants or other corrosive substances) to ensure long-term stability.


    Applicable temperature range

    The working water temperature can reach up to 45℃, which meets most industrial water treatment needs.


    Multiple optional ranges

    Three ranges are available: 0200 ppm, 02000 ppm, and 0~20000 ppm, which meet different needs from trace detection to high concentration detection.


    Advantages


    Accurate measurement

    Using a two-electrode system, it has high sensitivity and accuracy and can quickly respond to changes in hydrogen peroxide concentration.
    Low maintenance requirements

    Durable design and stable operation reduce maintenance frequency and cost.


    Widely used

    Applicable to various water treatment processes, including drinking water, industrial wastewater, sewage and circulating cooling water.


    Easy to operate

    Modular design and user-friendly interface for easy installation and use.


    High stability

    Not affected by water flow fluctuations, capable of long-term continuous operation, reducing the risk of instrument drift and data errors.


    Two-electrode system, used in all water treatment, mechanically strong membrane system, resistant to surfactants, high resistance to chemicals, maximum water temperature: 45°C, optional range 0~200/2000/20000 ppm​
