Human activity such as burning fossil fuels (coal, natural gas, and oil), solid waste, trees, and other materials, as well as some chemical reactions can release large amounts of CO₂ into the air. As such, continuous monitoring of carbon dioxide has become critical to compliance with every increasing government regulation for industry. Our CO₂ analyzers employ reliable Nondispersive Infrared (NDIR) technology for long instrument life and advanced optical filters for accuracy.

CO is a colorless, odorless gas that is naturally occurring but can cause sickness and death when present in large concentrations in ambient air. The gas is most commonly released as a by-product of fossil fuel combustion in vehicles and machinery and is a highly regulated pollutant. Our CO analyzers use advanced gas filter correlation technology to detect and measure CO gas concentrations in ambient air.

Sulfur dioxide (SO₂) is produced in significant quantity through the burning of fossil fuels during the production of energy and other industrial processes, including industrial transportation.  Sulfur dioxide can harm the human respiratory system and contribute to environmental pollution. Our sulfur dioxide analyzers measure up to 100ppm in ambient air using pulsed fluorescence technology.

Various nitrogen and nitrous oxide compounds (NO, NO₂, NO_Y, NO_x ) are emitted during agricultural, land use, industrial activities, fossil fuels combustion, solid waste management and the treatment of wastewater.  Our analyzers utilize chemiluminescence technology to measure the amount of nitrogen, and nitrous oxides in the air from sub-ppb levels up to 1000ppb.

Ozone, also known as trioxygen, is an inorganic molecule visible as a pale blue gas.  At high altitude, a layer of this gas provides protection against UV radiation from the sun.  Terrestrially, it is used as a powerful industrial oxidant and, even at very low concentrations, is harmful to animals and humans. Our ozone analyzers utilize UV Photometric technology to reliably detect and monitor Ozone.

Sulfur dioxide (SO₂) is produced in significant quantity through the burning of fossil fuels during the production of energy and other industrial processes, including industrial transportation.  Sulfur dioxide can harm the human respiratory system and contribute to environmental pollution. Our sulfur dioxide analyzers measure up to 100ppm in ambient air using pulsed fluorescence technology.

Zero air, or air that has been purified by removing pollutants such as NO, NO₂, O3, SO₂, CO, and hydrocarbons, is used to test and calibrate spanning ambient air analyzers during routine maintenance.  Other analyzers can be calibrated using a multi-gas calibration device that performs zero, precision, Level 1 span checks, audits, and multi-point routines in accordance with US EPA requirements. We offer zero air supply and multi-gas calibrators to keep your systems running at peak performance.

Calibrate ambient air and other gas monitoring instrumentation with our 146iQ Multi-Gas Calibrator, which generates gas standards. The output is used to calibrate instruments that perform zero, precision, Level 1 span checks, audits, and multi-point routines in accordance with USEPA requirements.
