SMART S-MS

Made with the refining and petrochemical industries in mind, the SMART S-MS is a SIL2 certified fixed gas detector designed to meet the most stringent industrial standards, with an optional aluminium or stainless-steel enclosure and HART and 3-relay card.

Where to Buy

The SMART S-MS is a safety integrity level (SIL) certified fixed gas detector ideal for flammable and toxic gas detection, made with heavy industries in mind.

Designed to meet the toughest industrial standards across oil and gas, refining and petrochemical industries, it comes with SIL2 hardware and SIL3 software. The SMART S-MS can also be personalised to your needs, with a choice of sensor head for specific gas detection capabilities, as well as a choice of transmitter (3-relay board or HART modem) and a choice of enclosure (aluminium / steel, number of entrances).
