used for continuous analyzing oxygen concentration automatically
Thermo magnetic oxygen analyzer , used for continuous analyzing oxygen concentration automatically, It not only applied in the power plant,cement workshop, chemical plant ,metallurgy etc whereas the process control system, also applied as monitoring instrument for the HBOC JRC-1020 in hospital.
Working Theory
The Oxygen has high paramagnetism, the oxygen has much higher magnetic susceptibility than other gas, so in the mixed gas, the magnetic susceptibility is subject to oxygen concentration, the mixed magnetic susceptibility show the oxygen concentration among them. ,
