With the CO2 meter you can ensure the right climate in your office. In addition to the CO2 content of the air, the CO2 meter measures the relative humidity and room temperature. The CO2 meter shows carbon dioxide concentrations up to 9999 ppm, temperatures from -10… 50 °C, and relative humidity values ​​from 20 … 95%. On the 3.5" display of the CO2 meter, the corresponding values can be read off directly, and the color of the CO2 display changes to provide an objective statement about the quality of the room air based on the CO2 content. This makes it particularly easy to assess the indoor air quality using the CO2 meter. For these reasons, the CO2 meter is particularly suitable for offices, schools, public buildings or hospitals, and in general for all buildings and rooms in which people are present.

The CO2 meter displays the measured values ​​numerically and graphically on the touchscreen. Operation is intuitive. The menu structure is simple and user friendly. In addition to setting the date and time, the user can parameterize offsets for the measured values ​​of temperature, humidity and the CO2 content. The display can be dimmed automatically, for example at night. The CO2 meter is operated via the mini-USB interface with a 5 V / 2 A power supply unit (not included).
