R448 Gas Detector - Explosion Proof Enclosure Version S3957R448

S3957448 - R-448 Gas Detector 0-2000 PPM, 4-20mA - Infrared sensor - Explosion Proof Enclosure Version SMART3G-D2 with Display Zone 1 Category 2 areas

S3957R448 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 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.
