R32 Gas Detector - Explosion Proof Enclosure Version S3427R32

S3427R32 - DIFLUOROMETHANE (R-32,HFC-32) Gas Detector 0-100% LFL, 4-20mA - Infrared sensor - Explosion Proof Enclosure Version SMART3G-D2 with Display Zone 1 Category 2 areas

S3427R32 SMART3G refrigerant gas detectors are employed to detect Difluoromethane, Freon 32, HFC-32, R-32, Carbon fluoride hydride, Methylene difluoride, Methylene fluoride, CH2F2 compounds (%LFL) 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.
