Ozone Monitor
Introduction
 |
BARC has developed an ozone monitor for measuring ozone concentrations at ppb levels (10-9 v/v ratio) in the ambient atmosphere. It is based on chemiluminescent reaction of ozone with ethylene supplied from a cylinder. Light produced in this reaction in the region of 300-500 nm is measured by a sensitive photomultiplier tube and the signal is processed and displaced on the meter and recorded by a recorder or data processor. Light produced in the reaction is specific to ozone and other pollutants do not interfere.
