## Long description

The BRESSER CO2 air quality monitor Smile (model 7004020GYE000) measures carbon dioxide concentration, temperature and humidity to help you maintain a comfortable indoor environment. Its compact design and continuous powered operation make it suitable for use at home or in the office. The device shows current CO2 levels on a colour LED display with a linear graphical scale and an intuitive smiley indicator for quick assessment.
Advantages
The monitor provides simultaneous display of CO2 concentration, temperature (°C/°F) and relative humidity with high precision, high resolution and fast response time. An adjustable ventilation alarm notifies you when CO2 exceeds a set limit (configurable up to 5000 ppm) and a humidity alarm can be set to indicate too dry or too moist air. The unit records maximum and minimum values for the last 24 hours and displays average values for the past 15 minutes and 8 hours. Powered by a mains adapter, it supports uninterrupted continuous operation.
Suitable for
Homes and apartments
Offices and meeting rooms
Classrooms and daycare facilities
Any indoor spaces where monitoring CO2, temperature and humidity is needed
