S2155AF - Formaldehyde, Methanal Gas Detector 0-100% LFL, 4-20mA - Catalytic sensor - Explosion Proof Enclosure Version SMART3G-C2 Zone 1 category 2 areas

S2155AF SMART3G gas detectors are employed to detect Formaldehyde, Methanal, Methyl aldehyde, Methylene oxide, Formol, Carbonyl hydride compounds (%LFL) in classified areas.

Designed to meet with industrial requirements, the SMART3G-C2 allow to monitor toxic, flammable and refrigerant gas contents in industrial environments and classified areas.
Ideal in industrial environments, the SMART3G-C2 feature one man calibration via the STS/CKD+ calibration keypad.
The SMART3G-C2 can reliably monitor flammable compounds (% LFL), toxic compounds and refrigerant gases in ppm, Oxygen and CO2 contents in % by Vol.
They do also monitor refrigerant gases both in ppm and % LFL.
The detectors are rated to IP65.
