The innovatively designed thermometer is a large display for monitoring the indoor air quality. This CO2 measuring device is used specifically to monitor indoor air quality in large rooms. These include, for example, meeting rooms, lounges or public spaces such as classrooms and kindergartens. Due to the large size of 388 x 288 x 43 mm, the CO2 indicator can also be easily read from a greater distance. With the wall bracket for the CO2 indicator, the large display can also be mounted anywhere on walls.

The NDIR CO2 sensor built in for the measurement has a measuring range of 9999 ppm. In addition to the high measuring range of the built-in NDIR CO2 sensor, the special feature of the CO2 measuring device is that the CO2 sensor does not require any maintenance. A temperature and a humidity sensor are also integrated in the CO2 measuring device in order to monitor the climatic conditions.

The CO2 measuring device also has a bar graph with which the measured CO2 content can be displayed graphically. The bar graph on the CO2 indicator is also divided into the colors green, yellow and red, which light up at fixed measured values ​​depending on the CO2 content. This makes it easier to assess the carbon dioxide in the environment so that ventilation measures can be carried out if necessary. To alert you to an excessively high CO2 concentration, the CO2 measuring device has an adjustable acoustic alarm, which is factory set to a concentration of 1200 ppm CO2.
