S3956R448 - R-448 Gas Detector 0-2000 PPM, 4-20mA - Infrared sensor - Explosion Proof Enclosure Version SMART3G-C2 Zone 1 category 2 areas
S3956R448 SMART3G refrigerant gas detectors are employed to detect refrigerant R-448 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-C2 allow to monitor toxic, flammable and refrigerant gas contents in industrial environments and classified areas.
Ideal in industrial environments, the SMART3G-C2 feature one man calibration via the STS/CKD+ calibration keypad.
The SMART3G-C2 can reliably monitor flammable compounds (% LFL), toxic compounds and refrigerant gases 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.
