Air Quality Meter Bresser Optics 7004020GYE000 CO2 Temperature 0-50°C

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

How to use

Place the monitor in a representative location away from direct sources of heat, drafts and windows for stable readings. Connect the device to the supplied power adapter and switch it on. Use the buttons to select units for temperature (°C/°F), configure CO2 and humidity alarm thresholds (CO2 up to 5000 ppm) and enable the audible alarm. Observe the colour LED display and graphical scale to check current CO2 concentration, temperature and humidity; a flashing arrow and audible alarm will indicate when ventilation is recommended.

Recommendations

Position the device at breathing height in the room, avoid placing it near doors, radiators or open windows, and ventilate the space when the CO2 alarm or the flashing indicator appears. Regularly check the memory readings to track indoor air quality trends.
