GFG ZD21 Oxygen Detector (5 year)
A very efficient transmitter for the detection of oxygen with an amperometric oxygen sensor consisting of an electrochemical oxygen "pump cell" based on zirconium dioxide. The measurement principle is characterized by an excellent long-term stability and selectivity.
The transmitter is an "intelligent" sensor with an extremely fast response time of t90 < 2 seconds. Moreover, it is very resistant to pressure and temperature changes variations or influences of humidity. It is also resistant to CO2 such that no damage occurs.
A wide measuring range is available from as low as 0.0 – 0.1% vol. up to 0 – 96% vol. The transmitter electronics facilitates use and maintenance and significantly increases the reliability and measurement accuracy.
