R449A Gas Detector - Dust Proof Enclosure Version S3922R449A

S3922R449A - R449A Gas Detector 0-2000 PPM, 4-20mA - Infrared sensor - Dust Proof Enclosure Version SMART3G-D3 with display Zone 2 category 3 areas

S3922R449A 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-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.
