TSI's new AirAssure™ Indoor Air Quality Monitors are available in three models, one measures 6 gases, one measures 4 gases, and one measures 2 gases - in addition to particulate matter, barometric pressure, temperature and relative humidity. designed to help you optimize your indoor air quality ventilation needs, while helping to achieve a safe and productive space. Utilizing low-cost sensor technology to continuously monitor gas and particulate pollutants along with essential IAQ parameters to help you achieve ideal indoor air quality.
The 2-gas AirAssure™ IAQ Monitor measures carbon dioxide (CO2), total volatile organic compounds (tVOC), particulate matter (PM), barometric pressure, temperature and relative humidity.
