Product Description

Details

Datasheet

APPLICATION:

The self-calibrating microprocessor-controlled CO2 and mixed gas measuring device is used for the detection of air quality and ⁄ or CO2 content in air within a range of 0 ppm to 2000 ppm CO2. Measuring signals are converted into standard signals of 0 -10V. The CO2 content of air is determined by a NDIR sensor. Self-calibration of the CO2 measurement takes place in cycles of ca. 7 days. In order to ensure this function, it is necessary to provide the device with fresh air (CO2 content 300 ... 400 ppm) at least once every 7 days. The air quality detection range is calibrated for standard applications such as monitoring in residential and conference rooms. The lifetime of the mixed gas sensor used for this purpose is limited. It depends on type and concentration of pollutant gases. When device-specific parameters are observed, the expected lifetime is at least 36 months.
