An ozone detector in the form of two basic embodiments which can measure ozone concentration in ambient air at 0.001-1 ppm. The first embodiment includes a stretched elastic material and a standard which can give ozone concentration in response to degree of microcracking or frosting of the elastic material. The second embodiment includes a chamber containing a long strip of elastic material wound on a spool, a small amount of manganese dioxide in the chamber to neutralize any ozone therein so that the ozone does not attack and frost the elastic material, a take-up spool mounted away from the chamber and adapted to wind the material from the chamber, a component for stretching the material, a light source for generating a tight beam and illuminating the film between the chamber and the take-up spool and a detector for the light beam after the light beam passes through the material.
