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.
Specifications
OZ1.2 | |
| Indicator | Ozone |
| Application | Swimming pool water, drinking water, service water, process water |
| Measuring system | Membrane covered, amperometric 2-electrode system |
Electronic | Analog version: - voltage output - not galvanically isolated electronics - analog internal data processing - output signal: analog (analog-out/analog) Digital version: - electronic is completely galvanically isolated - digital internal data processing - output signal: analog (analog-out/digital) or digital (digital-out/digital) mA-version: - current output analog - not galvanically isolated electronics - output signal: analog (analog-out/analog) |
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) |
