System for automatically measuring oxygen concentration

The invention discloses an automatic oxygen concentration measuring system, which belongs to the technical field of oxygen concentration measurement, and comprises a control end and a plurality of measuring instruments, a three-way electromagnetic valve group is arranged at a detection port of each measuring instrument, the three-way electromagnetic valve group and the measuring instruments are respectively connected to the control end through wires, an activated carbon cleaning module is arranged in the three-way electromagnetic valve group, and the activated carbon cleaning module is connected with the control end through wires. An adsorbent infiltration device is arranged on the three-way electromagnetic valve group; the device is convenient to operate and high in practicability, and effectively solves the problems that when the oxygen concentration of each temperature zone of the kiln is measured in the prior art, measurement points are more and cannot be measured at the same time, and dust rising due to
