Pack Size: box of 12 strips. Hazard Class /UN Number: Not Restricted. Storage Temp: Room Temperature. Ozone is a colourless toxic gas. It is irritating to eyes and mucous membranes and can cause respiratory complaints. An ozone content of 180 micrograms/ m3 is considered as critical value above which sensitive persons should avoid stronger physical exertion. The ozone values published by public media like press, radio or TV represent the ozone concentrations in the vicinity of the measuring stations. However, actual ozone values in other locations can considerably deviate from these published values due to meteorological and chemical influences such as wind, solar radiation, exhaust gases from vehicles etc. For this reason a local measurement of ozone concentrations is recommended.

Gradation of scale: less than 90, 90 -150, 150 - 210, greater than 210 micrograms/m 3 ozone
Method of application: Place a test stick in the open air, protected from wind. If necessary, fix the test stick with a piece of adhesive tape. After 10 minutes compare the test field with the colour scale on the container.
