S2155ST-LD - STYRENE Gas Detector 0-100% LFL, 4-20mA - Catalytic sensor - Explosion Proof Enclosure Version SMART3G-C2-LD Zone 1 category 2 areas

S2155ST-LD SMART3G gas detectors are employed to detect Styrene, Vinyl benzene, Cinnamene, Styrol, Phenylethene, Diarex HF 77, Styrolene, Styropol, Vinylbenzene compounds (%LFL) in classified areas.

SMART3G-C2-LD is designed to meet the needs of industrial applications and assures a reliable monitoring of toxic, flammable and refrigerant gas contents in classified areas.
The multi-color LED light ring assures an immediate visual indication of the detector status.
Ideal in industrial environments, the SMART3G-C2-LD feature one man calibration via the STS/CKD+ calibration keypad.
The SMART3G-C2-LD detectors can reliably monitor flammable compounds (% LFL), toxic compounds and refrigerant gases in ppm, Oxygen and CO2 contents in % by vol.
The detectors are rated to IP65.
