PROBLEM TO BE SOLVED: To provide a breathing air monitoring device which monitors a supplied air pressure of breathing air and gas concentration.SOLUTION: A breathing air monitoring device 1 includes: a gas concentration measurement device 5; a pipeline 2 for passing compressed air as breathing air; a branch passage 3 branched from the pipeline 2 for flowing a part of the compressed air as primary air thereinto; a pressure regulator 6 which reduces the pressure of the primary air flowing into the branch passage 3 to make the primary air into secondary air; and a first pressure sensor 71 which measures an air pressure of the primary air. The gas concentration measurement device 5 measures gas concentration of the secondary air.SELECTED DRAWING: Figure 2
