‘Luftgüte’ two relay indoor air quality infrared CO2 monitor with traffic light option

Measuring Range: 0-3000ppm CO2

Sensor sizes: Standard C3

Part no: 2112B8000-TLR

Power supply: 24V d.c.    Output: Traffic light option


Available for general low range CO2 monitoring and indoor air quality, the fixed monitor includes relay option to trigger downstream functions like ventilation. 

There is a simple green/yellow/red traffic light system with sad and happy faces illustrated on the front of the housing, which simply shows CO2 levels in the area. This monitor is popular for schools, offices and working areas and with the relay contacts, will trigger automatic ventilation such as window openers and fans to increase air flow and improve concentration! 

The monitor incorporates the C3 infrared sensor, which offers long-term stability in a compact, cost-effective package. The innovative material and construction of a double beam infrared measuring system ensures Carbon Dioxide is detected quickly and precisely with T90 response time of 30 seconds. A new digital algorithm evaluates and processes the measured signals, offering long-term stability in a lightweight, compact and cost-effective package.

The infrared measuring system detects the absolute Carbon Dioxide content of ambient air and monitors itself constantly, signalling if there is a malfunction of its hardware or software.
