Gas detectors with display for zone 2 category 3 areas

Designed to meet with industrial requirements, the SMART3G-D3 allow monitoring toxic and flammable contents in areas classified as zone 3.
They offer a 4-digit back-lit display and 5 mode status LED for the gas concentration reading.
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 (%LEL), toxic compounds in ppm. Oxygen and CO2 contents in % by Vol.
