SMART3G gas detectors are employed to detect flammable compounds (%LEL), toxic compounds (ppm), refrigerant gases, and Oxygen contents for both its depletion and enrichment in classified areas. The Pellistor sensors employed for the flammable Gas detection show excellent output linearity up to 100% LEL.

SMART3G-C has been specifically designed to offer high-performance products for industrial applications. SMART3G-D has been designed to meet tougher industrial requirements and offer a 4 digits back-lit display and 5 mode status LEDs for the gas concentration reading. They feature non-intrusive magnetic calibration for an accurate and easy calibration via Hall-effect switches, without opening the instrument and declassifying the area.
