WDK-07 Oxygen Gas Sensor For Medical Fields Such As Operating Rooms Intensive Care Units Emergency Departments
Working Principle:
It usually adopts an electrochemical sensing principle. The oxygen in the measured gas diffuses into the sensor through the diffusion layer and reacts at the working electrode, generating an electric current proportional to the oxygen concentration. This current signal is processed by the internal circuit of the sensor to obtain the oxygen concentration value.
Product Features:
- High - precision Measurement: Using high - quality sensing elements, it can provide accurate oxygen concentration measurement results, with an accuracy of ±1% F.S., which can meet the high - precision requirements of medical equipment.
- Good Temperature Adaptability: It can work stably in the temperature range of -20°C - +60°C, ensuring the reliability of measurement in different environmental temperatures.
- Long Service Life: The sensor has a service life of ≥2 years, which reduces the frequency of replacement and maintenance costs.
- Simple Installation and Operation: The installation is very simple, and the operation interface is user - friendly. Even medical staff who use it for the first time can quickly get started.
Applications:
The WDK-07 oxygen gas sensor is mainly used in medical fields, such as operating rooms, intensive care units, emergency departments, and home care. It is used to monitor the oxygen concentration in real - time during surgery, continuously monitor the oxygen of critically ill patients, quickly and accurately measure the oxygen concentration during emergency treatment, and provide a reliable monitoring tool for patients who need long - term oxygen inhalation.
