Product on quotation only Devis

The economical and precise HTRAM CO2 sensor is intended for schools, offices, restaurants and other establishments open to the public (PAB public access buildings) of small to medium size. It sounds an alarm under conditions that may increase the risk of exposure to viral transmission through breathed air.

Easy to use and very intuitive, this small CO2 detector allows you to monitor indoor air quality by indicating the carbon dioxide level, the temperature and the relative humidity level (hygrometry) in ambient air. The installation of CO2 sensors is increasingly presented as a relevant solution to the COVID transmission risks in confined spaces. Detailed description

Monitoring CO2 to prevent the Covid risk

Research conducted by scientists at the University of Colorado2,3 has shown that real-time monitoring of indoor ambient air can be 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.*

The HTRAM CO2 sensor to prevent the risk of Covid

The HTRAM CO2 sensor (Honeywell Transmission Risk Air Monitor) integrates three pre-programmed indoor activity parameters:

  • low activity: Cinemas, libraries and classrooms ...
  • Moderate activity: Restaurants, offices, small clinics ...
  • High activity: Sports halls, indoor stadiums, recreation centers ...

For each parameter, the monitor provides indications like a traffic light (green, yellow or red) and with the aid of an audible alarm, so that users are informed of the presence of conditions that may increase the risk of viral transmission through breathed air, based on detectable CO2 levels.

The HTRAM CO2 sensor analyzes specific air quality conditions and warns the user of conditions that may increase the risk of exposure to virus transmission through breathed air. It is recommended for spaces from 74 to 93 square meters. It does not prevent or reduce virus transmission, nor does it restrict viruses that may be present in ambient air.

The HTRAM Honeywell CO2 sensor

A simple and intuitive CO2 indicator

  • Green LED: Potentially low risk of viral transmission through breathed air
  • Yellow LED: Potentially moderate risk of viral transmission through breathed air: open windows and ventilate the room.
  • Red LED: Potentially high risk of viral transmission through breathed air: immediately ventilate the room, reduce activities, leave the room until the indicator goes down.

Features & Benefits of HTRAM Honeywell

  • Monitor carbon dioxide, Temperature and Relative Humidity

The HTRAM CO2 sensor communicates with a smartphone

The HTRAM can be connected via Bluetooth to a smartphone via the Transmission Risk Air Monitor by Honeywell application. This very intuitive application allows:

  • Select the level of activity in the room (low, moderate or high activity mode).
  • Customize the trigger points for each alarm (e.g. HSEs who want lower alarm triggering thresholds).
  • To consult the history of measurements over the last 90 days in the form of curves ...
