We are simplifying air quality monitoring

The Honeywell Transmission Risk Air Monitor helps you monitor CO2 levels, coupled with user-controlled settings to account for human activity levels in an indoor area and alerts the user when conditions are present that may increase risk of potential exposure to airborne viral transmission.*

Small - to medium - sized spaces like classrooms, restaurants, and buildings with outdated HVAC and ventilation systems can foster environments where the risk of potential airborne virus transmission could increase.

Research conducted by scientists at the University of Colorado1, 2 has shown that real-time monitoring of indoor ambient air can be an indicator of increased risk of potential airborne viral transmission, utilizing different levels of risk-based factors such as CO2 concentration levels and the type of human activity in the area.

Features & Benefits:
  • Monitor carbon dioxide, Temperature and Relative Humidity
  • Use non-dispersive infra-red (NDIR) sensor for more accurate monitoring
  • Three pre-programmed activity level settings (Low/Medium/High)
  • Traffic Light Visual Indication (Green/Yellow/Red) 
  • Sound Alert: one beep for medium alert; two beeps for high alert
  • Small portable size and light weight
  • Easy-to-use one button setting

*The Honeywell Transmission Risk Air Monitor (HTRAM) analyzes specific air quality conditions and alerts the user when conditions are present that may increase the risk of potential exposure to airborne viral transmission. It does not prevent or reduce virus transmission nor mitigate viruses that may be present, nor does it detect or warn against the presence of any virus, including but not limited to COVID-19. Even at lower risk levels caution is required to prevent viral transmission. The HTRAM does not repel or destroy any microorganism, viruses, bacteria, or germs.
