- Temperature sensor (Measuring range 0...+50°C)
- Humidity sensor (Measuring range 0...100 % rel. humidity)
- Humidity comparator function
- 5 binary and analogue inputs (e.g. for connecting an external temperature sensor)
- Clearly structured ETS
- Easy installation and mounting
- Modern design
- Flush mounting [55 mm]
- Fits in common switch range (55 x 55 mm)
- manual adjustment of set-point temperature via touch slider (adjustment range ± 3°, increment 0,5°)
- CO2 / rH - monitor
- Frame is not included in delivery
Information about CO2 and Covid-19
- Every person is emitting CO2 and aerosols e.g. during breathing. Today aerosols are claimed to be one of the transmission ways of SARS-CoV-2. CO2-concentrations can be measured and the correlation between the CO2 and the aerosol concentration can be used for analytical investigations, which use the measured CO2-concentration to calculate a likely aerosol concentration. (TU Berlin)
- A longer stay in small, bad or not ventilated room can increase the probability of a Covid-19 spread by aerosols even on bigger distances over 2 m. (RKI)
- The use of our CO2-sensors and the resulting room ventilation helps minimizing the risk of infection e.g. in schools or offices, gyms, restaurants or other premises where several people stay together.
