S2169HS - HYDROGEN SULPHIDE Gas Detector (H2S) 0-50 ppm, 4-20mA - Electrochemical Cell - Explosion Proof Enclosure Version SMART3G-D2 with Display Zone 1 category 2 areas

S2169HS SMART3G gas detectors are employed to detect Hydrogen sulfide, H2S, hydrogen sulphide, Dihydrogen monosulfide, Sewer gas, Stink damp, Sulfane, Sulfurated hydrogen Gas compounds (ppm) in classified areas.
For the toxic gas detection, Sensitron has operated a reliable selection among the most performing electrochemical cells to supply units representing the state of the art in toxic gas detection.

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.
