PROBLEM TO BE SOLVED: To provide a concentration measurement device that can be installed to a pipe with a large diameter or a storage bottle, for example, and further can be put into a branch pipe attached to a main pipe and therefore can precisely measure the concentration by phase measurement or power measurement or a combination thereof.SOLUTION: A concentration measurement device 40 is formed of parallel arrangement of a window material 3 of a microwave transmitting unit transmitting a microwave 7 to a measurement target 31 and a window material 4 of a microwave receiving unit receiving a microwave going through the measurement target 31. The microwave 7 is transmitted into the direction of the parallel arrangement of the window materials 3 and 4. |
