Crowcon smart 3NC Point Gas Detector

The Crowcon Smart 3NC Point Gas Detector is a point gas detector for safe areas, with several features for easy operation and maintenance such as ongoing system self-diagnosis, seamless installation and maintenance via handheld keypad and options for relay output and Modbus communication.


    Designed to be installed in non-classified areas and car parks, the SMART 3NC is an IP55-rated point gas detector for safe areas. Developed to provide an affordable solution for underground garages and non-hazardous locations, without compromising on sophisticated detection.

      Available for Methane, LPG, petrol vapours, CO, NO2 and CO2, these detectors use an industrial catalytic sensor for flammable gases, a three-electrode electrochemical cell for CO and NO2 and an infrared sensor for CO2.

        Offering seamless installation, the SMART 3NC’s maintenance and calibration can be done via the handheld keypad STS/CKD. At the same time, its ongoing system self-diagnosis ensures correct detector operation and performance.

          The Crowcon SMART 3NC Point Gas Detector also has Relay and Modbus communication options.
