How to measure, identify, and precisely locate gas emissions indoors?

Ellona’s POD2 ensures the safety of people and infrastructure by monitoring indoor air quality through real-time multivariate analysis. It measures up to 5 gases simultaneously (4 electrochemical sensors + 1 optical sensor) from a list of 21 possible gases (NO₂, SO₂, CO, O₃, NH₃, etc.). Its artificial intelligence algorithms accurately identify gas types, detect their interactions, and locate their sources. Through the EllonaSoft platform, smart alerts and automated corrective actions (ventilation, air purification) are implemented, ensuring a healthier environment, optimal occupant protection, and infrastructure preservation.

En savoir plus

Is the analysis of NH3 and H2S molecules enough to qualify and quantify odors (odours)?

No, the analysis of H2S (hydrogen sulfide) and NH3 (ammonia) molecules is not sufficient to assess all odors (odours) present in an environment. Although these molecules are commonly analyzed using electrochemical sensors, they only represent a fraction of the odor (odour) compounds. Hydrogen sulfide and ammonia are indeed important components of certain odor (odour) nuisances, but many other chemical compounds are responsible for varied and complex odors, such as aldehydes, volatile fatty acids, and mercaptans, which are not detected by these traditional technologies. This is precisely what the MOX (Metal Oxide Semiconductor) sensors used in Ellona devices, such as the WT1 Lite, the WT1 Pro (specifically designed for outdoor use), and the POD2 (adapted for indoor environments), are capable of detecting.
