CM 20 79134 CO2-Messgerät CM 20 Images 2 Back CO2 measuring instrument CM 20 | 79134 CO2 measuring instrument CM 20 in-stock items Documents Benefits Monitoring of room air qualitycompact designvisual indication of concentrationDesktop unit with USB-C connectionwith or without EnOcean® wireless technologyEEP (EnOcean® Equipment Profile): A5-09-09 Application For continuous monitoring of the carbon dioxide (CO2) concentration in the ambient air. Application in rooms in which many persons work, study or live and where carbon dioxide levels may consequently be elevated due to breathing, or in rooms where a very high air quality is required (for example, bedrooms, children's' rooms). High concentrations of carbon dioxide in the ambient air reduce the ability of persons to concentrate and perform. In addition, the concentration of aerosols increases with the CO2 concentration and, therefore, the risk of respiratory infections. Ideal for educational institutions, training/meeting rooms, office areas and household. Description Portable CO2 sensor with infrared technology in a plastic housing with USB-C interface for power supply. The CO2 concentration in the room air is indicated directly at the device by a colour scale:LED green: No ventilation requiredLED yellow: Ventilation recommendedLED red: Ventilation requiredWhen the device switches from green to yellow (approx. 1,000 ppm), a short signal tone sounds (<1 second) which is repeated every ten minutes. When the device switches from yellow to red (approx. 1,500 ppm), two short signal tones sound which are repeated every ten minutes. The signal tone can be disabled. The version CM 20E (with EnOcean® wireless module) sends the measured values to the AFRISOhome gateway for further processing and initiation of appropriate action. For example, it is possible to start a room ventilation system in order to reduce the CO2 concentration. The current carbon dioxide concentration and the history (day, week, month) is also displayed by the app AFRISOhome. This data is the ideal basis for ensuring healthy indoor ambient air. The AFRISOhome gateway in conjunction with additional AFRISO smart home products with EnOcean® wireless technology allows the user to configure a whole range of fully customisable, extensible applications.
