Chemiluminescence has long been recognized as the best practical analytical method for NOx detection at parts per billion level and with little or no interference from other pollutant gases. A sample containing nitric oxide is mixed with a large quantity of ozone. The nitric oxide reacts with the ozone to produce nitrogen dioxide in excited state. These excited molecules relaxes to ground state by emitting light in the region 600-2800nm which is measured using a photomultiplier Tube. The amount of light produced is proportional to the amount of nitric oxide in the sample.

Cleaning Cycle

Generally in a dust monitor, regular maintenance involves cleaning optical surface. Our systems are easily accessible due latched head design.
Toovercome manual cleaning, the systems come with apurge air systemwhich when connectedkeeps the contaminated stack gas away for the lens surfaces.
An aluminum air purge body is available for use on standard installations and a more advanced stainless steel body for more demanding installations.

APPLICATIONS:

Cement Plants
Steel Plants
Sponge Iron Plant
Power Plant
Oil & Gas industries.

Note- Analyzer for other gases like HCL, Cl2, O2, CO, NH3, CO2 etc with different range can also be provided.
