| |  MF 420-IR-Mobile Specification The measuring system determine with an infrared sensor a carbon dioxide of the air and a traffic light displays the air quality. Pictographs support are the simple displayed. Acoustic signals underline the optical ones. There is no need installation by an expert. The device can be put into operation simply by plugging the power supply unit into the socket outlet. Applications - special suitable for classrooms and all rooms with many persons

What is air quality ? Air quality is a measure in interiors for the quality of the air. Objective measurand of the air quality is the carbon dioxide (Co2).
This farb and odorless gas is breathed out by the man. The CO2 concentration hesitates between 360 ppm (parts by million) in pure air areas and 700 ppm in the open in towns.
The recommended maximum value for interiors is 1000 for ppm CO2, the limiting value for offices 1500 ppm.
The CO2 concentration rises depending on the pupil number and the size of the room strongly in the classroom during a lesson. Values of 3500 ppm aren't a rareness so. |
