Review: AirAssure an Indoor AQ Monitor by TSI

Someone may ask what more they can offer to an already saturated market of air quality monitors. The answer is simple: Experience! TSI Incorporated is a USA-based company with more than 60 years of experience and knowledge thanks to the 1000 researchers and engineers that work for the company worldwide. They hold more than 50 patents.

Recently, TSI released the AirAssure which is an IoT-enabled Indoor Air Quality Monitor (AQM) designed specifically for buildings that really need to have an in-depth and accurate view of the indoor air quality. The monitor comes in two versions the 4-gas and 6-gas variation. I am going to review the 4-gas AirAssure IAQM that comes with a Formaldehyde, Carbon Monoxide, Carbon Dioxide, and Total Volatile Organic Compounds sensors. Apart from the 4 or 6 gas sensors configurations, all versions come with a particulate matter sensor and a temperature/humidity/barometric pressure sensor. Also, a new CO2 and VOC model will be released this autumn.
