Information about themeasuring 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)

Accuracy

after calibration at repeatability

conditions (25°C, pH 7.2 in drinking water) of the upper full scale
- Measuring range 2 mg/l: at 0.4 mg/l <2%
at 1.6 mg/l <2%
- Measuring range 20 mg/l:
at 4 mg/l <1%
at 16 mg/l <3%

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 the measuring water)
Ambient temperature: 0 … +55 °C
Temperature compensation

Automatically, by an integrated temperature sensor
