CO₂ Panel – Clear Visual Display of Indoor Air Quality

When Visibility Drives Better Indoor Climate

CO₂ levels directly affect comfort, concentration, and well-being. However, without clear feedback, it is difficult to react at the right time.

In practice, this often leads to:

• Poor indoor air quality going unnoticed
• Delayed ventilation response
• Reduced productivity and comfort

The CO₂ Panel makes air quality visible – so action can be taken immediately.

Flexible Use – Standalone or Integrated

The CO₂ Panel can be used in different ways depending on your setup:

• Standalone use
• Direct display of indoor CO₂ levels
• Simple installation in rooms and shared spaces

Integrated with CL11 transmitter

• CL11 performs the measurement
• CO₂ Panel displays the data in real time

This allows you to combine system integration with user visibility.

Supports Better Ventilation Decisions

By making CO₂ levels visible, the CO₂ Panel helps improve how indoor environments are managed.

• Enables demand-based ventilation
• Helps users react to poor air quality
• Supports energy-efficient operation

Instead of running ventilation at fixed levels, you can respond to actual conditions.

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.
