A simple to use device that accurately measures ozone levels. Using specially treated Test Cards that react and change color when ozone is present provides readins for peak short term (one hour) and average long term (eight hour) periods. After exposure, compare the Test Card color change to the colormetric chart. This gives the average level of exposure of one hour, and eight hours. It does not provide minute-by-minute readings of increases or decreases in ozone levels. Can be used with the Zikua Card Reader.

Eco Badge Kit Contains: Eco Badge holder and snap-on clip, one hour test blocker, Eco Badge test cards, colormetric chart, article on ozone air pollution, vinyl (inner) storage pouch, vinyl (outer) pouch.
