S2157H2 - HYDROGEN Gas Detector 0-100% LEL, 4-20mA - Catalytic sensor - Explosion Proof Enclosure Version SMART3G-D2 with Display Zone 1 category 2 areas
S2157H2 SMART3G gas detectors are employed to detect Hydrogen Gas compounds (%LEL) in classified areas.
Designed to meet with tough industrial requirements, the SMART3G-D2 allow to monitor toxic, flammable and refrigerant gas contents in harsh environments and classified areas. They offer a 4-digit back-lit display for the gas concentration reading, 5 mode status LED and a high visibility multi-color LED light ring.
Ideal in harsh environments, the SMART3G-D2 feature nonintrusive calibration for an accurate and easy adjustment via Hall-effect switches, without opening the instrument and declassifying the area.
They can reliably monitor flammable compounds (% LFL), toxic compounds 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.
