For monitoring CO2 concentration in buildings where people are present, e.g. schools, offices, public institutionsBreathing good air is healthier, happier and more capable. Headache, dizziness and fatigue are often blamed for excessive concentrations of CO2 in the air. With the CO2 Monitor AIRCO2NTROL COACH from TFA, you can control how consumed and polluted the air is in rooms where people are staying, e.g. schools, offices, public facilities. Timely and energy-efficient ventilation ensures a healthy indoor climate.The monitor shows the current CO2 content of the room air, the temperature, air humidity and time on a display. The illumination color of the display can be used for quick evaluation and interpretation of the current CO2 measured values. Depending on the setting, the lighting directly signals the current air quality in the traffic light colors (green, orange, red). Alternatively, the red display light can be used as an optical signal in the event of an alarm if a certain limit value has been exceeded. You can also select a fixed color from seven colors or turn off the lighting altogether. The three smileys serve as a comfort zone indicator. If the smiling face is displayed, the air quality is optimal. In addition, the CO2 development of the last 24 hours can be clearly read on the graphic. The power is supplied via a suitable USB voltage source (PC, laptop).This text is machine translated.
