    Two-Wire 4-20mA Two-Electrode Ozone Sensor For Drinking Water, Direct Drinking Water, Service Process Water

    Two-Wire 4-20mA Two-Electrode Ozone Sensor For Drinking Water, Direct Drinking Water, Service Process Water


    Two-electrode system ozone sensor OZ1.2, used in drinking water, direct drinking water, service and process water, measuring water without surfactant, optional range 0~0.5/2/5/10/20ppm


    The functional characteristics of the ampere film ozone sensor include high sensitivity and fast response, which can accurately measure the ozone concentration in water. Its advantages are strong anti-interference ability, suitable for various water quality environments, and long service life. It is suitable for drinking water and industrial water treatment to ensure water quality safety.

    Information about the

    measuring range

    The actual slope of a sensor can vary production-related between 65% and 150% of the nominal slope

    Note: With a slope > 100% the measuring range is reduced accordingly.

    (Ex.: 150% slope → 67% of the specified measuring range)

    Slope drift
