Purecrea CO2 traffic light with smileys and bar display

Our CO2 meter measures the existing CO2 (carbon dioxide) levels in rooms using an infrared method and indicates when ventilation is necessary. The air we breathe also contains small aerosol particles; the higher the CO2 concentration in the room, the greater the likelihood that infectious aerosol particles, such as Covid-19, are present. The CO2 level is visualized through three smileys and a bar display, which is easily readable from a distance even in bright environments. The CO2 traffic light is suitable for use in large offices, meeting rooms, conference rooms, teachers' lounges, classrooms, or any situation where many people are gathered in one space. The CO2 traffic light features a light sensor and dims at night, ensuring that you are not disturbed by the light in dark rooms.

Info:
For larger quantities, we can customize the color of the front and housing according to your preferences and can also add promotional prints or logos.
