Designed to meet tough industrial requirements, the SMART3G-D2 allows to the monitoring of 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 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 contents in % by Vol. They do also monitor refrigerant gases both in ppm and % LFL.

The detectors are rated to IP65.
