Shows CO2 levels

Even a moderate concentration of CO2 can cause a lack of alertness, concentration and fatigue; high concentrations can be much more serious, even resulting in death.

The display also provides temperature and humidity values, together with the time and date. All parameters can be recorded to a USB flash drive and the data downloaded whenever the air quality needs to be analysed.

The CO2 sensor uses NDIR technology for precision and reliability; the Rotronic humidity sensor is the Hygromer IN-1. A mains power adapter is included.
