摘要
PROBLEM TO BE SOLVED: To provide an ozone concentration meter that not only measures ozone concentration in the air in a short time with high precision and good reproducibility, but also has convenience, economic efficiency and maintainability.;SOLUTION: The ozone concentration meter includes: a plurality of light sources comprising an LED 1 which has a light emission peak at a predetermined wavelength λ1 in a wavelength region showing ozone absorbancy in an ozone absorption spectrum, and an LED 2 which has a light emission peak at a wavelength λ2 showing ozone absorbancy of a half or less of ozone absorbancy for light emission from the LED 1; a cell for sample measurement in which sample air is held; and a plurality of detectors comprising a detector 1 and a detector 2 which measure light intensities from the light source 1 of the LED 1 and the light source 2 of the LED 2 before they are made incident on the cell for sample measurement and after they pass through it, respectively. The ozone concentration is found by a differential light absorption method using the ratio of the light intensities of the LED 1 and LED 2 measured by the detector 1 and detector 2.;COPYRIGHT: (C)2012,JPO&INPIT
