S2156PR - PROPANE Gas Detector 0-100% LFL, 4-20mA - Catalytic sensor - Dust Proof Enclosure Version SMART3G-D3 with display Zone 2 category 3 areas

S2156PR SMART3G gas detectors are employed to detect Propane, n-propane compounds (%LFL) in classified areas.
The Pellistor sensors employed for the flammable Gas detection show an excellent output linearity up to 100% LFL.

Designed to meet with industrial requirements, the SMART3G-D3 allow to monitor toxic and flammable contents in areas classified as zone 2.
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.
The SMART3G-D3 feature non intrusive 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 in % by vol.
