The ZD 22 transmitter is specifically designed for long-term monitoring of oxygen concentrations. The integrated amperometric oxygen sensor is based on an electrochemical oxygen pumping cell made of zirconium dioxide.
The integrated thermostatic control of the sensor element achieves accurate measuring results in the entire temperature range, regardless of the operating temperature. It can also be permanently used in environments with high concentrations of CO2 or in dry atmosphere.
The ZD 22 is available with a display or without display. The clear graphic display of the ZD 22 is self explanatory and allows you to read off the current status and other important information with ease. The display enables you to navigate effortlessly through the unit’s concise menu and to change settings or even calibrate, depending on your user authorization. In the event of an alarm, the display will turn red and two LEDs indicate the status.
