ULTIMA MOS-5 and MOS-5E detect ppm levels of hydrogen sulphide (H₂S), providing status indication and alarm outputs. Their performance is based on their metal oxide semiconductor sensor with unique technical parameters. High tolerance for a broad range of temperatures, humidity levels, as well as short-term high H₂S concentrations and very low cross sensitivity to common gases make these detectors ideal for installation in harsh environments. The ULTIMA MOS-5 provides analogue 4–20 mA and 3 relay outputs in a stainless steel housing. The ULTIMA MOS-5E incorporates analogue 4–20 mA and three open collector outputs in an aluminum housing. HART and Modbus communication enable complete status and control capability in the control room.
