The SMART 3-NC detectors are designed to offer cost-effective solutions with high-tech professional features for car parks and non-classified areas.

The SMART 3G-C2 is designed to meet industrial requirements, enabling the monitoring of toxic, flammable, and refrigerant gases in industrial environments and classified areas. Ideal for industrial settings, the SMART 3G-C2 features one-man calibration using the STS/CKD+ calibration keypad. These detectors can reliably monitor flammable compounds (% LFL), toxic compounds and refrigerant gases in ppm, as well as oxygen and CO2 levels (% by volume). The detectors are rated IP65 for protection against dust and water. Features: • Standard 4-20 mA 3 wire output • Optional 1 or 3 relay output • Optional RS485 interface for Modbus communication. • Zero tracking to maintain the zero point steady from possible drifts • Ongoing system self diagnosis • ATEX II 2G Ex db IIC T5 Gb (standard marking) (II 2GD with optional adapter) • ATEX II 2G Ex db [ib] ib IIC T6 Gb for detectors with intrinsically safe protection • SIL 2 HW & SIL3 SW certified

The SMART 3G-D2 is designed to meet rigorous industrial standards, enabling the monitoring of toxic, flammable, and refrigerant gases in harsh environments and classified areas. It features a 4-digit back-lit display for gas concentration readings, five mode status LEDs, and a high-visibility multi-color LED light ring. Ideal for use in challenging environments, the SMART 3G-D2 offers non-intrusive calibration for precise and easy adjustments via Hall-effect switches, eliminating the need to open the instrument and declassify the area. It can reliably monitor flammable compounds (% LFL), toxic compounds (ppm), oxygen and CO2 levels (% by volume), and refrigerant gases in both ppm and % LFL. Features: • Non-intrusive one man calibration via Hall effect switches • 4-digit display and 5 mode status LEDs • Multi-color LED light ring • Standard 4-20 mA 3 wire output • Standard 3 relay output • Optional RS485 interface for Modbus communication. • Zero tracking to maintain the zero point steady from possible drifts • Ongoing system self diagnosis ATEX II 2G Ex db IIC T5 Gb (standard marking) • ATEX II 2GD Ex db IIC T5 Gb (II2 GD with optional adapter to be specified at the order) • ATEX II 2G Ex db [ib] ib IIC T6 Gb for detectors with intrinsically safe protection • SIL 2HW & SIL3 SW certified • IP rating IP65
