Oxygen Sensor MED-O2-LA

  • MED-O2-LA.png


The MED-O2-LA oxygen sensor is a galvanic electrochemical sensor. Oxygen undergoes a reduction reaction on the working electrode and an oxidation reaction occurs on the anode material and releases charges to form an electric current. The magnitude of the generated current is proportional to the partial pressure of oxygen and obeys Faraday's law. We can determine the size of the oxygen partial pressure by testing the size of the current.


* Low power consumption
* High precision
* Wide linear range
* Excellent repeatability and stability

The oxygenator uses molecular sieve physical adsorption and desorption technology to adsorb nitrogen in the air and obtain high-purity oxygen after purification. The current oxygen therapy and oxygen health care equipment is roughly divided into health care oxygen machines with an oxygen concentration of 30%-60%, molecular sieve medical oxygen generators with an oxygen concentration of more than 90%, oxygen cylinder with higher oxygen concentration,and portable oxygen cylinders.
