What is a Carbon Dioxide Monitor?
CO2 Monitors are designed to monitor the air in areas such as classrooms and offices, or anywhere the presence of multiple occupants can create poor air quality.
These low-cost units alert room users via a simple traffic light indicator system that CO2 levels, humidity and temperature may have risen, and increased ventilation is needed. The simple action then needed is just to open windows or other mechanical ventilation devices to reduce the CO2 in the room.
Unlike Carbon Monoxide, Carbon Dioxide is non-toxic and poses no risks to health at low levels, but for learning and working environments, and to help reduce the spread of viruses, these devices vastly improve the well-being and productivity of building occupants.

EASY TO READ TRAFFIC LIGHT SYSTEM
The indicators on the monitor will change when CO2 is increasing in the room, this will happen when occupancy levels rise. The CO2 monitor will always be above 400ppm as Carbon Dioxide is in the air we breathe out.
Green ( 400—800ppm ) Good air quality
Amber ( 800-1500ppm ) Improve ventilation
Red ( >1500ppm ) Improve ventilation further
You can improve the ventilation by opening windows or turning on any existing mechanical ventilation and the level of CO2 will decrease gradually. If the level of CO2 is high there is no immediate risk to health.
FAQs
A Carbon Dioxide monitor detects the level of Carbon Dioxide in the room. By monitoring the Carbon Dioxide in the air it gives you an indication of the air quality.
A Carbon Dioxide monitor gives the occupants of the room an indication of air quality and when they need to take action to improve the ventilation. Good air quality is essential for a healthy learning or working environment. A well-ventilated room reduces the transmission of airborne viruses.
Carbon Dioxide is naturally occurring in the air we breathe, however when a classroom or office has increased occupancy the level of Carbon Dioxide can increase too, this is because Carbon Dioxide is a by-product of people breathing in and out.
Open the box, you will find the Carbon Dioxide monitor and your user manual.
Insert the AC power adapter to supply power and turn on the backup power switch. It takes 3 minutes to preheat the product after starting up.
The built-in backup polymer lithium battery, can support AC power after 12 hours of work;
When AC is powered, the traffic light indicator window is always on, while when the backup battery is powered, the traffic light indicator window flashes.
Try to locate the monitor away from any sources of ventilation such as windows to ensure you are getting an accurate reading for the room.
The screen gives you an indication of the level of Carbon Dioxide in the room.
Pay particular attention to the traffic light LEDs on the left-hand side of the monitor.
Green indicates good air quality no action needs to be taken.
Amber/Orange indicates Carbon Dioxide is increasing in the room.
If the indication goes to Red above 1500ppm there is no need to panic, but you should take some action. This indicates that the Carbon Dioxide level in the room is increasing and you should introduce some fresh air such as opening a window or turning on some mechanical ventilation if available. The levels will gradually decrease as fresh air is introduced to the room.
If your CO2 monitor is constantly showing red, it probably means you need more ventilation in the room.
Don’t confuse Carbon Dioxide with Carbon Monoxide. We all know Carbon Monoxide as the silent killer, however, Carbon Dioxide is non-toxic and poses no risks to health at low levels found in classrooms and offices.
