MSA Ultima X Series gas monitors now provide an extended hydrogen sulfide detection range of up to 500 ppm. These detectors offer the latest mechanical and electrical technologies and are designed to perform in virtually any gas detection application.

Ultima XA and XE monitors provide continuous monitoring of combustible and toxic gases and oxygen deficiency, using catalytic and electrochemical technologies.

XA Monitors have all-purpose plastic enclosures designed for NEMA 4X rating, while the XE monitor offers explosion-proof monitoring with a 316 stainless steel enclosure.

Advanced features of the Ultima X Series include:

  • Disconnect-under-power allows sensors in an explosion-proof unit to be changed without the need for hazardous area declassification cation.

  • Interchangeable smart sensors are easy to install and replace. New sensors are recognized, triggering automatic alarm and relay setting reconfiguration.

  • Display conveniently alternates between sensor reading and gas type and features scrolling diagnostic messaging.

  • Design features one electronics board for reliability and serviceability. Multiple-entry mounting enclosure enables problem-free installation and servicing.

  • Onboard LEDs and relays provide increased indication of alarm and fault conditions. “Quick-check” LEDs can be viewed from afar, and field-programmable alarm levels and normally energized/de-energized and latching/non-latching relay functions offer three levels of alarm and a fault.

These units can operate on a stand-alone basis, or they can be connected to a control system (eg, PLC, DCS) via a standard 4- to 20-mA output.
