TSI's IAQ-Calc Indoor Air Quality Meter 7525 is an outstanding instrument for investigating and monitoring indoor air quality (IAQ). Model 7525 simultaneously measures and data logs multiple parameters such as carbon dioxide (CO2), temperature, and humidity; and calculates dew point, wet bulb temperature, and % outside air.
