S2157AV - VINYL ACETATE Gas Detector 0-100% LFL, 4-20mA - Catalytic sensor - Explosion Proof Enclosure Version SMART3G-D2 with Display Zone 1 category 2 areas

S2157AV SMART3G gas detectors are employed to detect Vinyl acetate, Ethenyl acetate, Ethenyl ethanoate, Acetic acid vinyl ester, acetoxyethene, VyAc, VAM, zeset T, VAM vinyl acetate monomer, acetic acid ethenyl ester Gas compounds (%LFL) 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.
