DatasheetDesigned to be installed in non-classified areas and car parks, the Sensitron 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.
