PRODUCT DETAILS

TSI AirAssure™ 8144-2 Indoor Air Quality Monitor

The TSI AirAssure™ 8144-2 is designed for continuous indoor air quality monitoring in schools, offices, healthcare facilities, commercial buildings and industrial environments. It monitors key air quality parameters to help facility teams understand indoor conditions and identify potential concerns.

When connected to TSI Link™ Solutions, users can remotely view real-time readings, analyse historical trends, generate reports and manage multiple monitors through a centralised cloud platform. Custom alerts can also be configured to notify users when selected air quality levels are exceeded.

Parameters Monitored

Carbon Dioxide Monitors CO₂ levels to support ventilation assessment and occupied-space management.
Volatile Organic Compounds Detects changes in VOC levels that may be associated with indoor materials, cleaning products or other sources.
Particulate Matter Tracks airborne particulate matter to provide greater visibility into indoor air cleanliness.
Temperature Monitors indoor temperature conditions for occupant comfort and environmental assessment.
Relative Humidity Tracks humidity levels that may affect occupant comfort and indoor environmental conditions.
Barometric Pressure Measures atmospheric pressure as part of continuous environmental monitoring.
