Oxygen analysis system uses imported special materials to effectively absorb the toxic components in the sample gas and send them to the explosion-proof oxygen transmitter, thus ensuring the service life and accuracy of the explosion-proof oxygen transmitter. The user can control the corresponding nitrogen supply device by collecting the oxygen concentration value measured by the system, thereby reducing the concentration of flammable and explosive gas in the centrifuge and the reaction kettle, thereby providing safety for production.
