W&T: timeair

Ventilate correctly based on real CO₂ values

timeair by Wiesemann & Theis determines and visualises the time until the next necessary air exchange. The sensor measures the CO₂ concentration of the ambient air every 10 seconds and calculates on this basis the remaining time until the critical limit value is reached. This can be individually configured in a range from 700 to 3000 ppm. When the critical value is reached, visual and optionally also acoustic signals are triggered.

• CO2 air quality sensor: Measuring range 400-5000 ppm CO2
• Remaining time display and alarm function: LED 7-segment display for measured value and remaining time, LED coloured ring to indicate remaining time and alarm, LED CO2 traffic light display
• Operating elements: 3 touch sensors for unit configuration
• Power supply: DC 5V via micro USB socket
• Plastic housing for wall mounting or magnetic attachment to whiteboard or similar, IP20
• Dimensions: Ø 88mm x 18.9mm

• Monitoring CO2 levels - at home, in the office, at events, in daycare centres and schools
