Honeywell Transmission Risk Air Monitor

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

• The monitor comes with a user manual and USB charging cable. AC adapter sold separately.
• Made of alloy and plastic, the monitor’s sleek, lightweight design makes it easy to carry for real-time monitoring anywhere.
• Red, yellow, and green indicators show at-a-glance the potential airborne transmission risk level of the air you are breathing

As the world returns to in-person activities, engaging in additional measures to help support the health of the public is vital. Classrooms, restaurants, and buildings with outdated HVAC and ventilation systems can foster environments where the risk of airborne virus transmission could increase.* Honeywell proprietary technology that monitors CO2 levels, coupled with user-controlled settings to account for human activity levels in an indoor area, provides users with a portable, cost-effective, and user-friendly solution that alerts to a potential increased risk of airborne viral transmission. Research conducted by scientists at the University of Colorado1 has shown that real-time monitoring of indoor ambient air can provide an indicator of increased risk of airborne viral transmission, utilizing different levels of risk-based factors such as CO2 concentration levels and the type of human activity in the area.



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.
