VOC sensor
High-performance measurement device for determining the VOC value in the room air, optionally available with sensors for relative
humidity and temperature. The integrated switching output (relay) can be used to directly control a fan or window lifter.
The measurement device has an LED display with three colors (green/yellow/red).
Air quality
Measuring range
450 - 2000 ppm (CO² equivalent)
Accuracy
±100 ppm
Output scaling
450 - 2000 ppm at 0 - 10 V
Display
3 LEDs
Green: < 800 ppm (air quality good)
Yellow: 800...1200 ppm (air quality moderate)
