Air quality sensors are devices that ensure safety and protect the health of people in a given room. They are used primarily in heating, ventilation and air conditioning installations in various types of buildings: office buildings, shopping centers, public utility premises or single-family houses. They are also used in industry.


Air quality sensors are designed primarily to measure the concentration of carbon dioxide, as well as other dangerous or unpleasant substances such as cigarette smoke, hydrogen, carbon monoxide, ethanol or ammonia. The sensors can also be used to measure the level of vapors emitted by furniture, carpets, paints and adhesives. The main task of air quality sensors is to detect components that are hazardous to health in the room, which are often odorless and therefore imperceptible to people staying in it. The sensors protect against the negative effects of bad air, informing about the exceeded standards on an ongoing basis. As a result, the user is able to react quickly and take action to improve air quality.



Who is the air quality sensor for?


Air quality sensors are simple devices with easy installation and intuitive operation. They should be an obligatory element of any modern building automation system. Our store's offer includes a wide selection of professional air quality sensors, thanks to which we are able to find a product that meets the requirements of each installation. We offer, among others, models intended for installation in the duct and on the wall, as well as outdoor air quality sensors. Depending on the customer's requirements, we have versions with and without a display, and those that, apart from controlling the level of carbon dioxide, simultaneously measure the room temperature and humidity. The available solutions are calibrated in accordance with applicable standards, thanks to which they are characterized by high measurement accuracy.



Professional air quality sensor and its application


The air quality sensors we offer can be used as an element of large installations managing the operation of ventilation, air conditioning or cooling systems in modern office buildings and public buildings.
