Eco Badge

• use eco badges to measure the presence of ground level ozone 

With the Eco Badge®  it is possible to take two readings: a one-hour peak exposure and an eight-hour average exposure, calibrated in ranges of 10 ppb to 350 ppb.  The pretreated Test Card will change color after exposure to ground level ozone.  The amount of exposure can be determined by comparing the Test Cards to an Eco Badge Colorimetric Chart.

2.  Remove the silver wrapped Test Card sheet from the sealed pouch.  With scissors cut along the dotted line.  Remove the sheet of Test Cards.  Separate one Test Card from the sheet.  They are perforated and tear easily.

3.  Place the Test Card sheet back into the silver wrapper.  Put the wrapped Test Cards back into the sealed pouch.  Make sure that all the air is forced out of the pouch.  It is important to limit the Test Card exposure to air.

4.  Insert the individual Test Card into the slot at the top of the Eco Badge.

5.  Insert the One Hour Test Blocker in front of the Test Card.

6.  Insert the plastic strap of the clip through the hole at the top of the badge and attach using the snap.

7.  Wear the Eco Badge or place it in the test area for eight hours.  When finished, remove the exposed Test Card and on the back record the time, date, location, and exposure level.

8.  The exposure level can be determined by comparing the Test Card to the Eco Badge Colorimetric Chart.
