Cirius Infrared Gas Sensors

Our Cirius range of standard infrared gas sensors incorporate patented technology and provide raw detector signals for users to interface to their own IR circuitry and software. Using a novel optical technique our sensors offer high sensitivity to target gases whilst having an extremely small sensing volume. Housed in an industry standard 20mm diameter package they are available as “basic format” 7 pin sensors.
