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

At repeatability conditions

(25 °C, pH 7,2 in drinking water)

   Approx. <- 1% per month

 

Working temperature

Measuring water temperature: 0 … +45 °C

(no ice crystals in measuring water)
  Ambient temperature: 0 … +55 °C

Temperature

compensation

Automatically, by an integrated temperature sensor
Sudden temperature changes must be avoided

 

 

Max. allowed working pressure

Operation without retaining ring:

- 0.5 bar

- no pressure impulses and/or vibrations

Operation with retaining ring in Flow cell:

- 1.0 bar,

- no pressure impulses and/or vibrations (see option 1)
