Features & Applications:
This Alnor indoor ait quality carbon dioxide meter is the ideal tool for investigating indoor air quality and performing thermal comfort studies. It simultaneously measure and data log multiple parameters: carbon dioxide (CO2), temperature, humidity, and calculates dew point, wet bulb temperature, and % outside air. Ideal applications include investigating indoor air quality, performing thermal comfort studies, checking ventilation systems and conducting IAQ evaluations.
