SMART 3NC

The SMART 3NC is a point gas detector for safe areas, with a number of features for easy operation and maintenance such as on going system self-diagnosis, seamless installation and maintenance via handheld keypad and options for relay output and Modbus communication.

Où acheter

Designed to be installed in non-classified areas and car parks, the SMART 3NC is a 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, while its ongoing system self-diagnosis ensure correct detector operation and performance at all times.

The SMART 3NC also has Relay and Modbus communication options.
