R449A Gas Detector - Dust Proof Enclosure Version S3921R449A

S3921R449A - R449A Gas Detector 0-2000 PPM, 4-20mA - Infrared sensor - Dust Proof Enclosure Version SMART3G-C3 Zone 2 category 3 areas

S3921R449A SMART3G refrigerant gas detectors are employed to detect R-449A compounds (ppm) in classified areas.

For aggressive atmospheres, where the Pellistor sensors would be seriously damaged, Sensitron developed a range of detectors employing industrial grade Infrared sensors: IR sensors are poison free and this grants a higher accuracy and a longer lifetime to the cell.

Designed to meet with industrial requirements, the SMART3G-C3 allow to monitor toxic, flammable and refrigerants contents in areas classified as zone 2, category 3.
Ideal in light industrial environments, the SMART3G-C3 feature one man calibration via the STS/CKD+ calibration keypad.
They can reliably monitor flammable compounds (% LFL), toxic and refrigerants contents in ppm, Oxygen and CO2 in % by vol.
