Product Description:
YJJ WDK-07 Electrochemical Oxygen Sensor Oxygen Battery - Used for Measuring Oxygen Concentration In Medical Equipment
Features:
Oxygen Sensor
Full-scale linear output
Works without external power supply
Temperature compensation
Fast response
Accurate and reliable
Strong anti-interference ability
Product Description
The WDK-07 oxygen sensor is an electrochemical sensor specifically designed for measuring oxygen concentration in medical equipment. The interface model is 5520257-2. It adopts a molded body design and features fast response and long service life. It can achieve domestic substitution and provides excellent quality for customers while reducing costs.
The difference between this sensor and the WDK-06 oxygen sensor lies in the pin definitions. Application scope
The WDK-07 oxygen sensor does not require an external power supply when in operation. It has been professionally and accurately calibrated and temperature compensated at the factory and can be used as a sensing component in oxygen analyzers, such as oxygen generators control devices, medical ventilators, anesthesia equipment, incubators, etc.
