IO-Scan

Cost-effective, real-time assessment of indoor air quality in the form of air exchange rates
Verify and optimise the effectiveness of ventilation systems in occupied areas
Ability to evaluate aerosol reduction through the interaction of window ventilation, building ventilation system and mobile room air cleaners

Self-calibrating measuring system
Deviation from previous trace gas measurements should be within 10%.
Real-time results can detect and evaluate the influence of changes in the ventilation system during the measurement process
Intended measurement depth in the room: 1 m to 50 m

The introduction of mist aerosols into the room air influences the light transmittance to be measured.
Transmittance of an air-aerosol mixture and use of measured transmittance to determine air exchange rate
Integral real-time optical measurement over individual indoor distances
