Applications:
This ozone badge may be used for personnel or area monitoring for
exposure times ranging from 15 minutes to 2 days.
Cross Interferences:
Chlorine does not affect the performance of the monitor. Hydrogen peroxide is a
known interference. Up to 0.3 ppm nitrogen dioxide shows no interference.
Exposure to 0.5 ppm nitrogen dioxide for 5 hours causes false positive readings
equivalent to 0.04 ppm ozone; exposure to 1 ppm nitrogen dioxide for 3 hours
causes false positive readings equivalent to 0.04 ppm of ozone. No further
interferences are known.
