## Summary description

The Bresser Optics 7004020GYE000 is a grey CO2 temperature meter designed for precise measurement of carbon dioxide levels and temperature ranging from 0 to 50°C. Its compact size makes it suitable for various environments, ensuring accurate monitoring of air quality.

## Long description

The Bresser Optics 7004020GYE000 Grey CO2 Temperature Meter is a compact indoor air quality monitor that measures CO2 concentration, temperature and humidity. It provides clear, real‑time readings on a colour LED display and includes a graphical CO2 indicator with a smiley face and linear scale so you can quickly assess air quality at a glance.
Advantages
The device combines CO2, temperature (°C/°F) and humidity measurements on a single, intuitive LED display 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 warns of too dry or too humid conditions. The meter also stores minimum and maximum values for the last 24 hours and calculates averages for the last 15 minutes and 8 hours. Continuous operation is possible using the included power adapter.
Suitable for
Homes and apartments
Offices and meeting rooms
Classrooms and daycare facilities
Small shops and service counters

How to use
Place the meter in the room where you want to monitor air quality, away from direct drafts and heat sources for accurate readings. Connect the power adapter to enable continuous operation. Read the CO2, temperature and humidity values directly from the LED display. To set an alarm, configure your preferred CO2 or humidity threshold (CO2 up to 5000 ppm) and activate the alarm with the button. When thresholds are exceeded the device emits an audible alarm and the display shows a flashing arrow reminder to ventilate.
Usage recommendations
Position the Bresser CO2 Temperature Meter at breathing height in the main occupied area, avoid placing it near windows, HVAC vents or radiators. Use the ventilation alarm to establish a regular airing routine; for classrooms or meeting rooms, consider a lower CO2 threshold to maintain occupant alertness. Check the min/max and average values to evaluate ventilation effectiveness over time.
