Detailed Product Description

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

Technical Data

1. OZ1.2 (analog output, analog internal signal processing)
A potential-free electrical connection is necessary as the sensor electronic is not equipped with a galvanical
isolation.
