B1-C Ozone Badge – How To
Ozone badges are quick, easy, and cost effective methods to determine ozone levels in occupied spaces. These badges are easy to use, and quick references for ozone detection that are gaining popularity due to the low cost.
An Ozone Badge uses a strip of dyed paper that will become discolored by oxidation from ozone. The rate of discoloration over time will indicate the ozone level in the ambient air surrounding the badge.
The B1-C Ozone Badge is a new badge that provides 5 uses, or ozone detection strips. There are 5 small circular discs of dyed paper that are covered with a protective strip. When the protective strip is removed the colored disc will begin to be discolored by the ozone in the room. After a period of time that color change can be correlated to the color change indicator for an ozone reading.
Below is an image of the inside of a B1-C detector card showing the instructions for use.
As you can see from the instructions above the colored indicator gives 4 levels of ozone to match your colored disc (sensor) against. This colored disc must be evaluated after the time span indicated, 10 minutes for indoor measurements, or 20 minutes for outdoor measurements.
For example, the sensor should be exposed by removing the protective strip for 10 minutes in indoor locations. After 10 minutes match the sensor strip to the corresponding color indicator, if that is #2, the resulting ozone level is 45-75 ppb.
Higher ozone levels
If the sensor becomes a darker color than the indicator in the time span specified the ozone level is greater than 105 ppb. If this is the case take another measurement exposing the sensor to ambient air for half time time, 5 minutes for indoor measurements, or 10 minutes for outdoor measurements. The color change can now be evaluated to the color indicator, the resulting ozone level must be taken x2 for accurate readings.
For example, the sensor should be exposed by removing the protective strip for 5 minutes in indoor locations. After 5 minutes match the sensor strip to the corresponding color indicator, if that is #2 the resulting ozone level is 90-150 ppb.
