Test Strips are not intended for applications requiring high accuracy readings, rather, they are designed and used for semi-quantitative and for screening purposes.

Ozone Test Strips are designed to provide a quick indication of ambient levels of ozone in both indoor and outdoor air.

• Economical and easy-to-use
• Direct-reading
• Can be used in any location
• Fast, on-the-spot results

Principle of Operation:

Ozone test strips are chemically treated to react with ozone. Easy-to-use, place a test strip in the area to be tested. After 10 minutes, compare the test strip with the color scale on the test strip package. Results display in four distinct colors from light yellow to dark yellow. Each represents a certain level of ozone concentration. Ranging from 0.045 ppm to over 0.105 ppm.

Ozone Concentrations
A ~ up to 0.045 ppm (45 ppb)
B ~ from 0.045 ppm to 0.075 ppm (45 - 75 ppb)
C ~ from 0.075 ppm to 0.105 ppm (75 - 105 ppb)
D ~ over 0.105 ppm (105 ppb)

ppm = parts per million
ppb = parts per billion

Packaging: 12 Ozone Test Strips packaged in a moisture-proof tube with instructions.
Ozone Test Strips have a three-month shelf-life after the container is opened.
