Time for fresh air

B+B VOC-probe - for a pleasant indoor climate
VOC Fühler (PresseBox) (Donaueschingen, ) This high-power sensor shows exactly when it‘s time to ventilate your living space or business premisses.
Installed in a wall housing it measures the air quality (VOC* fumes), humidity and temperature. The measured value is displayed by LEDs.
The sensor has 3 LEDs (green, yellow and red) with those the current VOC-content is displayed:
Green: < 800 ppm (good air quality)
Yellow: 800…1200 ppm (okay air quality)
Red: > 1200 ppm (bad air quality)
The probe is available in a simple version which just measures VOC and in a version with a rely which measures VOC, temperature and humidity. With the relay a fan or window regulators can be controlled.

*VOC describes gaseous and vapourous evaporation from humans, furnishing, walls etc. like hydrocarbon, alcohols, aldehyds and organic acids. like hydrocarbon, alcohols, aldehyds and organic acids.
