TSI IAQ-Calc 7500 Series Indoor Air Quality Meters

TSI's IAQ-Calc meters are exceptional instruments for investigating and monitoring indoor air quality. These IAQ instruments simultaneously measure and data log multiple parameters to monitor indoor air quality conditions, so you can pick the IAQ device that best suits your needs.

Model 7515 measures CO2 only. Model 7525 measures CO2, temperature, humidity, percent outside air, dewpoint, and wet bulb temperature and includes datalogging. Model 7545 measures the same as the 7525, but adds the ability to measure CO.
