OZONE MONITOR

                                                                                                              

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.

SPECIFICATIONS 

Measuring ranges  : 0-100 ppb
: 0-1 ppm
: 0- 10 ppm
Minimum detection limit  : 5 ppb
Response time (10% to 90% rise) : 5 sec
Reproducibility : +1%
Linearity : +1%
Output : 0 - 1 volt (for air quality data processor)
Power requirements : 100 watt at 230 v, 50 Hz

APPLICATIONS

Ozone monitor can be used for measuring ambient levels of ozone in polluted urban atmospheres and near high voltage power distribution centres.
