Available for general CO2, indoor air quality or industrial monitoring, the C3 infrared sensors offer long-term stability in a compact, cost-effective package. Available as sensors with 4-20mA transmitters or as complete housed solutions. These also offer calibration software.

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.
