Frequent measurements of CO2 are not enough
Why is it beneficial to have the air quality sensor, if you already have a ventilation

The concentration of CO2, which was measured at the stand of our company for the entire duration of the fair, was relatively high. Given that this is the most modern exhibition hall in Prague, we would expect that the ventilation will be resolved satisfactorily.

On Wednesday 21st November, when the attendance was the highest values ​​exceeded1700 ppm, which is already an alarming value at the maximum recommended level of 1,000 ppm.
The values ​​of CO2 were measured by a data logger, which evaluates the measured data in the form of graphs and tables in the computer, but for monitoring and control ventilation should be sufficient even the most basic products measuring CO2.
