Product Summary
The WDK-09 is an electrochemical oxygen sensor for oxygen concentration measurement and is
designed specifically for medical equipment. WDK-09 oxygen sensor interface model is 5520257-2 The
sensor adopts molded body design, provides fast response and has long life. Domestic substitution can
be realized. The sensor provides customers with superior quality while reducing costs.
The pin definitions of WDK-09 oxygen sensor and WDK-06 oxygen sensor are different.
Application Scenarios
Using WDK-09 requires no external power supply. Sensors have been calibrated before leaving the factory.
To avoid the influence of temperature, temperature compensation function is applied in sensors. WDK-09 can be
used as the sensing component in oxygen analyzer, such as control component in oxygen generator, medical
ventilator, anesthesia equipment, incubator.
