The breath of man contains a considerable proportion of C02 when you exhale, so that in the presence of people in an area of C02 in the air slowly rises, leading to fatigue and loss of concentration. The C02 content of pure air is currently at approximately 350 ppm. The C02 monitor CM2 allowing for an increase of C02 content a needs airing either manually or automatically via the visual display of the analog output The C02 monitor CM2 is used to monitor indoor air quality.

The C02 monitor CM2 allowing for an increase of C02 content a needs airing either manually or automatically via the visual display of the analog output signal. The measurement of C02 content is based on the dual wavelength NDIR method. An infrared emitter emits light in a cuvette of two adjacent wavelengths on a receiver. C02 is located in the beam path, is the characteristic wavelength of the C02 weakened and provides a signal for the evaluation. The evaluation provides an output signal of 0/4...20 Furthermore, in the front cover of the unit, the C02 content visually displayed on a 6-segment LED display in the colors green, yellow and red. The electronics is in a white plastic case mounted for wall mounting. The case can also be mounted on a flush-mounted box. The device is powered measuring methode: time interval measurements: optical display: supply voltage: ambient temperature: current consumption approx. 100 mA plastic, white, wall mounting or mounting on physical dimensions connection switching C02-Monitor CM2 for monitoring the C02 concentration in rooms range: 0...2000 ppm C02, optical display with 6 LED outputssignal: -please specify- case: plastic, white, for wall mounting or mounting on a switch box 75 x 127 x 25 mm (w x h x d) www.grillo-messgeraete.de • Email: [email protected] • Webshop: www.sensor-store.de
