Air Matters has recently purchased an ozone monitor. This is especially useful for measuring low levels of ozone in workplaces or in ambient air. The monitor reads in real time and data logs to help relate peaks to various activities.
Ozone can have serious effects on lungs and is produced in welding, plasma cutting, corona discharges, some laundry applications etc. Let us know if you would like to discuss any aspects of ozone health effects or monitoring.
