Abstract:
A sensing element in which a dye that changes in the light absorption characteristic of the visible region upon reaction with ozone gas is deposited in the pores of a porous material is prepared. A change in dye before and after exposing the sensing element to a measurement environment for a predetermined time is measured. The ozone gas amount in measurement target air is measured on the basis of the change in dye.
