MSA Ultima X Series Gas Monitor

In June 2017, MSA launched the ULTIMA X5000 as our new flagship gas detector and transmitter. This successful launch, with its expanding sensor offering and technological advances that increase safety while reducing the total cost of ownership, will serve as a direct replacement for the ULTIMA X and its derivative products (ULTIMA XE, XP, XA, XIR, TriGard, TriGas, etc.), effective December 31, 2020.

The ULTIMA X5000 was designed and intended to eventually phase out the ULTIMA X, as it mounts in the exact physical location with ease. The conduit entries, standoffs, and mounting bolts are located in the same place, allowing for installation using existing cabling.

Support of the ULTIMA X product line will continue for at least 5 years after discontinuation.

MSA’s Ultima X Series Gas Monitors are microprocessor-based transmitters engineered with the customer in mind. Utilising DuraSource Technology for extended sensor life, the monitors are available in either stainless steel or polycarbonate enclosure housings.

The HART Field Communications Protocol provides increased sensor data, part of cost-effective asset management. HART also provides convenient setup, calibration and diagnostics. Calibrate, set up or perform diagnostics with HART from any point along the 4-20 mA line. HART also allows existing component installation and wiring to be used, reducing installation costs
