The TSI 8144 AirAssure monitors are designed to keep building occupants informed about the indoor air quality of the building. Easy to operate these WiFi enabled devices come as 2, 4 or 6 gas models. All include the measurement of carbon dioxide (CO2), Total Volatile Organic Compounds (tVOC), particulate matter (PM2.5 and PM10), temperature and humidity, with the 4 gas model additionally measuring Carbon Monoxide(CO), and Formaldehyde (H2CO), and the 6 gas model measuring Ozone (03), Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Carbon Monoxide (CO), Total Volatile Organic Compounds (tVOC) and Carbon Dioxide (CO2).
The TSI 8144-2 (2 gas) model is designed to help users monitor and manage common air pollutants typically found in building spaces such as livings spaces, hallways, offices and conference rooms
The TSI 8144-4 (4 gasses) model use is similar to the two-gas version except that this also measures formaldehyde (a common volatile organic compound), so it is ideal for rooms with pressed wood building materials or furniture, cigarette or fuel-based smoke, and other textiles or glue.
The TSI 8144-6 (6 gasses) model measures ozone (O3) and nitrogen dioxide (NO2) levels. O3 monitoring is important for buildings with copy machines or electric arc welders. NO2 monitoring is important for industrial facilities with welding fumes or other emissions, and for buildings with gas stoves and other unvented appliances.
