NO/NO2/NOX Analyzer uses Chemiluminescence which is the best practical analytical method for NOx detection. When an NO (nitric oxide) molecule reacts with ozone, it is oxidized to NO2, in an excited state. A small fraction of the molecules in this excited state decays by emitting a photon (i.e. giving off light) in the near infrared portion of the spectrum. The concentration of NOx in the sample is determined by the amount of light emitted from the mixed gas sample. This technique provides an extraordinarily sensitive, selective, and linear measurement of NOx. |

CO Analyzer measures carbon monoxide by passing infrared light through sample and determining the absorbed energy and then compare this to that absorbed by a reference gas. This is accomplished with a Gas Filter wheel which alternately allows a high energy light source to pass through a CO filled chamber and a chamber with no CO present.

The Ozone Analyzer is a microprocessor-controlled analyzer for measuring low ranges of ozone in ambient air. An Ultraviolet light is passed through a sample cell. The light is absorbed, depending on the amount of ozone present. The true value of the ozone is proportional to the absorption. |

Chemiluminescent NH3 Analyzer measures ambient ammonia in selectable ranges from 0-50 ppb to 0-2,000 ppb using the chemiluminescence principle and an API designed external ammonia converter and sampling system Ranges are user selectable in 1 ppb increments and auto ranging is available. Ammonia is difficult to measure accurately because of a tendency to be absorbed into other materials. |

TRS provide a dependable, accurate and convenient method of measuring hydrogen sulfide or Total Reduced Sulfur (TRS) in levels commonly required for Ambient Air monitoring, offering ranges from 0-50 ppb to 0-10 ppm. Both analyzers convert sulfur gases to sulfur dioxide and measure concentrations using fluorescence technology. |

The H2S analyzer provides a dependable, accurate and convenient method of measuring hydrogen sulfide in levels commonly required for Ambient Air monitoring, offering ranges from 0-50 ppb to 0-10 ppm. The analyzers convert sulfur gases to sulfur dioxide and measure concentrations using fluorescence technology.
