Ventilation and air conditioning systems
A good working climate goes without saying nowadays in most companies, at least from a technical point of view – ultimately, there are high-performance ventilation and air conditioning systems in modern workplaces. However, it is important that these systems always have the optimum settings and maintenance.

The adjustment of volume flows at larger air inlets and outlets – particularly at swirl outlets – can be a challenge. However, it doesn't need to be! We are setting new standards with our new, exceedingly light testo 420 volume flow hood, including App connection for smartphones/tablets.
Ventilation duct
Observance of air flows in the ventilation duct is of utmost importance for the function of the ventilation and air conditioning system.
- Accurate recording of air flows in the ventilation duct
- Ensure the removal of room loads (heating, cooling and substance loads)
Air outlets
Every duct inlet and outlet should only contain the volumetric flow that, according to its calculations, is the basic requirement for a system that works efficiently.
- Measure the volumetric flow according to EN 16211 in a reliable way
Pressure on filters
Air conditioning systems are equipped with filters which prevent dirt from the outside air entering the indoor air.
- Measure differential pressure to check whether the filter is still fully functional
- If the pressure is too high, the filter is contaminated and needs changing
