Complete and versatile gas detection series

For more than 36 years, Sensitron, part of the Halma Group, has been recognised as a trusted leader in the design and production of gas detection systems. Among its most established solutions, the SMART 3G series represents a complete and versatile range of detectors, designed to ensure reliable protection in industrial environments, both in classified and non-classified areas.

SMART 3G detectors are engineered to monitor a wide spectrum of gases, including flammable, toxic, refrigerant and oxygen, and can be equipped with catalytic, infrared, PID and electrochemical sensors depending on the specific application. This flexibility makes them suitable for numerous industries, ranging from oil & gas and chemical plants to power generation, refrigeration systems and food storage facilities. 

Robust and dependable, SMART 3G detectors guarantee accurate and timely detection even under harsh operating conditions. With ATEX and IECEx certifications, as well as SIL2 hardware and SIL3 software compliance, they meet the strictest standards for functional safety and reliability. This combination offers maximum confidence to operators, system integrators and end users alike. 

Within the range, the SMART3G-C2 is a compact detector designed for monitoring toxic, flammable and refrigerant gases. It supports one-man calibration via the STS/CKD+ keypad, simplifying maintenance and reducing downtime. The device ensures precise measurement of flammable compounds (% LFL), toxic and refrigerant gases in ppm, and oxygen and CO2 in %vol. Depending on the application, it can be configured with the most suitable sensor technology, ensuring efficiency and accuracy in every context. 

To meet different installation requirements, the SMART3G-C2 is available in multiple versions: with display (SMART3G-D2) for immediate data visualisation, or without display but equipped with an LED ring (SMART3G-C2-LD) for clear and intuitive status indication. By combining advanced technology, robust certifications and practical design, the SMART 3G series delivers a comprehensive solution to the challenges of industrial gas detection. 

Sensitron continues to strengthen its commitment to developing innovative solutions that protect people, plants and processes, ensuring safety with precision.
