CO2 and Indoor Air Quality
The amount of carbon dioxide had been virtually constant at 280 ppm (particles per million) – i.e 280 gas molecules per million air molecules – the last ten thousand years. However in recent years, this measured value has been increasing rapidly at approx. 2 % per year.
A high level of CO2 in the air within a room causes headaches, tiredness and lack of concentration. The regulation on CO2 concentration was established in order to evaluate IAQ (Indoor Air Quality). Normal atmospheric air in so-called ‘clean air areas’ has a level of 360 ppm and approx. 500 ppm in urban areas. The limit of 1,000 ppm (“Pettenkofer Figure”) is still seen as being adequate indoor-air quality, which is especially important when regarding all meetings and conference rooms, as well as schools and open-plan offices. As a guideline for school rooms in the USA the limit of 1,000 ppm applies; for workplaces the occupational exposure limit is 5,000 ppm.

OPUS20: How can the data be recorded in the internal memory of the OPUS20?
The OPUS20 must be configured in Mode M3 REC or M4 REC Hide. This can be done using the configuration button on the back of the OPUS20.
OPUS20: What are the eletrical specifications for the PoE version of the OPUS20 device?
The OPUS20 PoE version uses a voltage level of 48V and the lowest current level
OPUS20: Is ethernet communication available for all OPUS20 versions?
Yes, the etherent interface is a part of all OPUS20 instruments, so all of them cam be connected to the network (LAN)
