Bad air at the Prague Exhibition Centre

The CO₂concentration that was measured at our company’s stand throughout the fair was quite high. Considering that this is the most modern exhibition hall in Prague, we could expect the ventilation to be more satisfactorily solved.

On Wednesday, 21 November, when the highest levels of visitors were recorded, the values exceeded 1700 ppm, which, with the maximum recommended limit of 1000 ppm, is already an alarming value. The CO2 values were measured with a data logger, which evaluates the measured data in graphs and tables on a computer, but for monitoring and controlled ventilation, even very basic CO2 measuring products would be sufficient.
