Category: Air Quality Measurement
The Honeywell Transmission Risk Air Monitor is an easy-to-deploy, portable device that measures carbon dioxide and features a proprietary risk alerting system based on different activity levels within a room. This allows end-users to proactively improve indoor ventilation.
The Honeywell Transmission Risk Air Monitor (HTRAM) analyses specific air quality conditions and alerts the user when conditions are present that may increase the risk of exposure to airborne viral transmission.
The Honeywell Air Monitor is a cost-effective monitor for use in schools, restaurants, and other small-to-medium-sized buildings that alerts to the potential increase of exposure to airborne transmission risk based on CO2 and activity levels in an indoor area. It is also perfect to use if you are working from home, to make sure you have enough ventilation.
Key Features


Using this guidance and Honeywell algorithms, we developed risk levels based on common activities and average variables such as room size, number of people present, breathing rate, and duration. The device comes with three pre-programmed indoor activity settings: low activity (movie theatres, libraries, and classrooms), medium activity (restaurants, offices, small clinics), and high activity (gyms, indoor arenas, recreation centres) and is recommended for coverage of 800-1000 square feet. For each setting, the monitor provides indications using a traffic light pattern (green, yellow, or red) and a sound alarm so users can be aware of the potential increase of airborne transmission risk based on detectable CO2 levels.

Bluetooth Functionality
The HTRAM has Bluetooth functionality. It is possible to configure the device and view data history through the mobile app.
