Rotronic
CO₂ Panel — Panel-Mounted CO₂ & Climate Display System
Clear, reliable carbon dioxide and climate monitoring for rooms and controlled environments
Accurate carbon dioxide (CO₂) measurement is essential for maintaining indoor air quality, energy efficiency, safety and compliance — whether in commercial buildings, schools, labs or industrial facilities.
The Rotronic CO₂ Panel delivers continuous, easy-to-interpret CO₂ readings alongside key climate parameters like temperature and relative humidity in a sleek, panel-mounted format. Designed for installation in walls, control panels or monitoring stations, this solution gives you real-time insight into air quality and environmental conditions.
Product Overview
The Rotronic CO₂ Panel system integrates a high-accuracy CO₂ sensor (based on Non-Dispersive Infrared – NDIR) with supportive climate measurement — giving a complete snapshot of ambient conditions from one instrument. It can be used as a standalone display or linked to building automation systems for control and logging purposes.
Typical measurements include:
- CO₂ concentration
- Temperature
- Relative humidity
The robust panel design ensures clear visibility and durability in everyday operation, while the embedded electronics support reliable measurement and simple integration.
Sensor Technology
High-accuracy CO₂ measurement is achieved with NDIR (Non-Dispersive Infrared) sensing — a proven technology for stable, long-term performance with low drift. The CO₂ Panel reads air samples via an integrated probe or remote sensor depending on installation configuration.
Key capabilities include:
- Rapid response to changing CO₂ levels
- Stable baseline with automatic self-calibration options
- Minimal maintenance and long sensor life
- Clear digital display with intuitive read-outs
CL11 CO₂ Transmitter Compatibility
The Rotronic CO₂ Panel pairs especially well with the CL11 CO₂ transmitter, a dedicated humidity-compensated CO₂ sensor optimized for environmental monitoring. The CL11 sensor provides:
- NDIR CO₂ detection with automatic humidity correction
- Ranges suitable for indoor air quality applications
- Compatibility with analog and digital (Modbus) outputs
Together, the CO₂ Panel and CL11 form a robust monitoring station for:
- Classroom and office air quality
- Conference and meeting spaces
- Production and processing environments
- Cleanrooms and controlled labs
CO₂ Principles
Carbon dioxide (CO₂) is a colorless and odorless gas that naturally occurs in the Earth’s atmosphere — but in high concentrations, it can be hazardous. The natural concentration of CO₂ outdoors is about 0.04 % (400 ppm). When humans and animals exhale this gas, it mixes rapidly with the surrounding air — even in well-ventilated rooms.
A high concentration of CO₂ becomes noticeable when people start to feel tired, drowsy, or lose concentration. This effect develops faster in smaller rooms with many people present, such as conference rooms or classrooms.
To take appropriate countermeasures — such as adding fresh air — it is important that modern climate control systems measure not only humidity and temperature, but also CO₂ concentration. The CO₂ level is widely recognized as a key indicator of indoor air quality.
