Ventilation and air conditioning systems

A good indoor climate is a matter of course in today’s companies. Advanced ventilation and air conditioning systems ensure the best possible conditions in workplaces. Making these systems work optimally requires careful settings and continuous maintenance.

Indoor climate and comfort level

Here you will find measuring products to regularly measure and monitor the quality of the indoor climate and the comfort level in all possible environments.
Accurate metrics allow for precise settings of climate parameters, resulting in satisfied tenants and top-performing staff.

Measurement of air quality

Indoor climate

  • Evaluate air quality by e.g. carbon dioxide measurement
  • Carbon dioxide levels should not exceed 1000 ppm
Measurement of turbulence level

Turbulence level

  • Provides indication of air change and intensity of air flows
  • Accurate measurements of air temperature and turbulence
Measurement of thermal radiation

Thermal radiation

  • The WBGT index is used to evaluate workplaces affected by thermal radiation.
  • In accordance with DIN 33403 and ISO 7243
Measurement of comfort level

Comfort level (PMV/PPD)

  • All parameters included in a PMV/PPD measurement
  • Assessment of average climate value
  • In accordance with ISO 7730
Measurement of sound level


  • Clarifying the sound environment in homes and workplaces
  • Detect unwanted, disturbing sounds from equipment or people

Localize energy losses and overheating.
