Product specification

Indoor air quality is becoming increasingly important. After all, a good indoor climate promotes health and well-being. It also increases performance. This is particularly important in schools, offices and public buildings. Basically, anywhere where many people are present at the same time.

But when is the air we breathe "good air"? In closed rooms, CO2 concentration is one of the most important factors. The higher the concentration, the worse the air.

Yet CO2 stays under the radar of human senses. We can neither see it nor smell it. We only notice its effects, such as fatigue and dizziness. Or those of a viral disease. Because the probability of transmission increases with the CO2 load: the more exhaled air there is in the room, the greater the danger of becoming infected with the coronavirus, for example, via aerosols.

With the AIRCO2NTROL UP Dual Beam CO2 Monitor, you have a permanent overview of air quality. Its display shows the current CO2 content of your room air. In addition, the temperature and humidity appear in its lower display area.
With your new air control system, you can now ventilate in time and constantly maintain a good indoor climate.

How does CO2 monitoring work with the AIRCO2NTROL UP Dual Beam from TFA? A high-quality NDIR Dual Beam sensor measures the current CO2 content in ppm (parts per million). "Dual Beam" means that, with each regular measurement, there is always a second control and calibration measurement to ensure a permanently stable measurement.
The exact result is then visualised on the display, as a measured value and as a bar on a circular, graphic display. A traffic light display additionally illustrates the value. Green indicates good air. Yellow, blue and red warn of increasingly bad air.
Values up to 600 ppm are considered ideal, by the way. The sensor of this device has a measuring range of 400 ppm to 5000 ppm.
An acoustic alarm assists you in monitoring. You can set the upper limit for the alarm signal yourself.
It stores the maximum and minimum values of the last 24 hours for CO2, room temperature and humidity. These can be called up at the touch of a button.

The result: many useful measurement results at a glance. Its high-contrast display and smartphone design make this CO2 monitor distinctive. Thanks to its integrated stand, the device is stable and can be placed anywhere.

The AIRCO2NTROL UP Dual Beam CO2 Monitor has an integrated battery, rechargeable from the mains. When fully charged, the unit can be operated for 12 hours independently of the mains.
This monitor comes complete with a 1.5 m long USB cable and power adaptor.
