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.
