IAQ-CALC^™
Indoor Air Quality Meters

Models 8732, 8760, 8762 TSI's IAQ-Calc™ Meters are exceptional instruments for investigating and monitoring Indoor Air Quality (IAQ). The Model 8732 is a cost-effective meter for CO2 measurements. The Models 8760 and 8762 simultaneously measure and data log multiple parameters to monitor indoor air quality conditions. The Model 8760 measures CO2, temperature, humidity, and calculates dew point, wet bulb temperature, absolute humidity, humidity ratio and % outside air. The Model 8762 adds CO.
