The Sensitron SMART3G-D2 fixed gas detector has sensor options for detecting more than 50 toxic, flammable, and refrigerant gases. It is ideal for a variety of industrial applications and harsh environments. The device features non-intrusive calibration, a 4-digit back-lit display for the gas concentration reading, a 5-mode status LED, and a high-visibility multi-colour LED light ring.

Non-intrusive calibration

Ideal in harsh environments, the SMART3G-D2 features non-intrusive calibration for an accurate and easy adjustment via Hall-effect switches without opening the instrument.

Wide variety of gas and sensor options

The SMART3G-D2 has options for detecting over 50 flammable, toxic and refrigerant gases. ``

Safety Integrity Level (SIL) certification

The SMART3G-D2 is SIL2 hardware and SIL3 software, with a redundant system, the hardware is SIL3.
