Miniature air quality monitoring systems

Taking into account the effects of increasing air pollution on human health, Cairpol allows new real-time measurement possibilities of pollutants (gas, odor or particulate) even at very low concentrations.

Completely autonomous and able to detect ppb pollution levels, Cairpol miniature sensors cause a great stir in the air quality monitoring world, with an installation cost level never being so low until now.

Initially designed to warn asthmatics of real-time pollution levels, Cairpol patented technology finds many applications within the industrial fields. One such application is fugitive emissions monitoring networks, which previously was too costly with conventional monitoring systems.

With its compact, autonomous, easy to set up, sensitive and reliable sensors that can be used even in extreme conditions, the radio frequency communication systems and ultra low power consumption, Cairpol systems can be networked to provide optimal coverage and measurement of air pollution over a vast area from a single computer.

Cairpol systems can be used for fugitive emissions and odor measurement on industrial sites like waste water treatment plant (WWTP), landfill, compost plant, along a street or motorway, or in any sensitive area…

Cairpol monitoring systems also offer the possibility to measure continuously pollutant levels in workshop atmospheres, houses and public buildings.


Recognition on the rise for Cairpol in the US

Cairpol keep getting more and more credits from the USEPA and is used in a growing number of their studies. The technology of the Cairsens/Cairclip sensors is definetly of present interest, and is part of the new paradigm of air quality monitoring.

Implementation of the modeling feature on a Cairnet Odorous Gases network brings advanced functions of site pollution mapping and reverse dispersion and allows therefore the identification of the source with great accuracy.

Plants are often spread over wide areas: the monitoring of odorous gases is mainly based on solutions composed of analyzers and modelling technologies. Some systems integrating one or a few analyzers coupled to dispersion models are already available but, because of the low density of measurement points and of the algorithms used, they are not able to provide a full reliable picture of emissions allowing real-time management of processes.



Using the Cairnet Odorous Gases network application, it is now possible to obtain this real-time accurate picture of the gases dispersion and its source, allowing the user to promptly take action on the concerned processes. With its extensive coverage, highly accurate measurements and this new modeling feature, Cairnet Odorous Gases network is a really cost-efficient tool for any user willing to monitor its emissions.

These unique features were presented in June 25th-28th, 2013 at the A&WMA annual conference in Chicago (support documents available for downloading). The field results already obtained through two installations of 24 H2S Cairclips and 24 NH3 Cairclips in two separated compost plants have been displayed.
