Measuring the CO2 concentration and temperature for energy-efficient, demand-controlled regulation of the room climate.
- Selective measurement of the CO2 concentration and temperature for demand-controlled ventilation of rooms (e.g. meeting rooms, conference rooms, offices, classrooms, etc.)
- 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
- The sensors have been developed according to the DIN EN 13779, DIN EN 15251, VDI 6038 and 6040 directives
- Mounting flange supplied
