MSA Ultima XE

MSA Ultima® XE (XP) Gas Monitor


The ULTIMA XE gas detection instrument is available with catalytic sensors for flammable gases and electrochemical sensors for toxic, and oxygen flammable gases.



All ULTIMA XE instruments are protected by a rugged, explosion-proof stainless steel housing and are suitable for indoor and outdoor applications in virtually any industry, including offshore operations.

The monitoring instruments can be used as stand-alone units, but are also equipped with a 4-20 mA output for connection to controllers. In addition, the ULTIMA X³ range now supports ModBUS RTU communication with PLC, DCS or other control systems.

Features and Benefits

  • Stainless steel explosion proof housing with multiple lead-throughs;
  • Large LCD for numeric data and clear text messages;
  • Combined sensor electronics for multiple sensing and monitoring technologies;
  • The design on a single circuit board considerably simplifies service work;
  • "Quick-check" LEDs indicate system conditions, with good visibility even from a distance;
  • Optional field programmable relays;
  • Remote sensor option;
  • Automatic compensation for changes in temperature and humidity;
  • All calibrations and adjustments are made using a non-invasive calibrator or controller. The housing thus remains closed; (IR interface)
  • Sensors can be changed in the field under voltage, even in hazardous areas (catalytic and electrochemical sensors)
  • 4-20 mA output signal (ULTIMA XE)
