S2155OE - ETHYLENE OXIDE Gas Detector (ETO) 0-100% LEL, 4-20mA - Catalytic sensor - Explosion Proof Enclosure Version SMART3G-C2 Zone 1 category 2 areas

S2155OE SMART3G gas detectors are employed to detect Ethylene Oxide, ETO, 1,2-Epoxyethane, Dimethylene Oxide, Oxacyclopropane, Oxiranne compounds (%LEL) 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.
