                    O2-A3 Oxygen Gas Sensor for Safety Applications Medical Field

 

Application Scenarios:

  • Safety Applications: Since it can accurately measure oxygen concentration and has good environmental adaptability, it is suitable for use in places where ensuring the safety of personnel in terms of oxygen levels is crucial, such as mines, confined spaces, and industrial plants.
  • Medical Field: Although specific medical applications may require further adaptation and compliance with relevant medical standards, it can potentially be used in some medical gas - related equipment like oxygen concentrators, oxygen analyzers, medical gas alarm systems, and anesthesia machines.
  • Air Quality Monitoring: To monitor the oxygen content in the air, which can provide data support for environmental research and air quality assessment.

Electrical and Mechanical Considerations:

  • The sensor is a plug - in replacement sensor for hand - held gas detectors that use an O2 - A3 sensor.
  • Manufacturers do not recommend soldering to the pins. Pin sockets can be purchased from Andon distributors. Users can click on the relevant link on the distributor's website, select the brand PDF, find the sensor, and then search for the Andon part number for the sensor's socket.
