Measuring the CO2 concentration for energy-efficient control of the room climate.
- Selective measurement of the CO2 concentration for demand-controlled ventilation of rooms (e.g. meeting rooms, conference rooms, offices, classrooms, etc.)
- Available in 2 versions: with and without temperature measurement
- CO2 measurement with NDIR1) Dual-beam technology, therefore stable in the long term and largely resistant to external influences
- Suitable for 24-hour operation
- Calibrated ex works and ready to use immediately
- Very fast response to changes in the CO2 concentration in rooms
- Temperature-compensated calibration for the standard air pressure of 1013 mbar
- The sensors have been developed according to the DIN EN 13779, DIN EN 15251, VDI 6038 and 6040 directives
