Oxygen Analyzer and Auto Change Over System


What is Oxygen Analyzer???

Ultrasonic gas flow and oxygen sensor implements the ultrasonic velocity difference between upstream and downstream to detect the gas flow and also to measure the oxygen purity. It is a reliable and low cost sensor for integration into PSA, medical and personal oxygen generators

Applications of Oxygen Analyzer


  • PSA Oxygen Generator
  • Medical Oxygen Generator
  • Personal Respirator
  • Oxygen Concentrator
  • Anesthetic Apparatus
  • High Pressure Oxygen Storage

What is Auto Change over System

The Auto Change Over System takes care of the system when the machine is under maintenance or shutdown. We recommend to keep a stand-by cylinder bank in parallel with Auto Change Over System which will handle the emergency in case of power failure or maintenance of the system.
