X5000 Gas Detector

Years ahead of its time, not to mention its competition.

The ULTIMA® X5000 Gas Monitor is the future of gas detection . Featuring MSA XCell® gas sensors with TruCal® technology that corrects sensor drift and offers calibration cycles up to 24 months. The gas transmitter's advanced, multi-lingual OLED display is easy to read and the unique touch-screen interface makes it simple to navigate. Identical footprint and wiring as the ULTIMA X series makes retrofits simple.

Recalibrate your expectations.

MSA’s patented XCell® sensors with TruCal® technology and Diffusion Supervision, extends calibration cycles up to 24 months for H2S and CO gases. TruCal technology actively monitors the sensor integrity and compensates for environmental factors that cause traditional electrochemical sensors to drift, allowing calibration cycles to be extended well beyond industry standards. An industry first, Diffusion Supervision warns if sensor inlet becomes blocked and unable to detect gas. Learn more about TruCal

XCell Gas Sensor Technology

  • Available also for Ammonia, Chlorine, Oxygen, Sulphur Dioxide and Combustible gases
  • Better stability and accuracy, fast response time
  • Three-year industry leading warranty
  • Five-year expected sensor life


2 sensors. 1 transmitter. 0 compromises.

Dual sensing technology doubles the sensing power with half of the footprint of a single gas transmitter. Sensors can be remotely mounted, mixed and matched to suit your gas detection needs.



The ULTIMA X5000 is equipped with an Organic LED (OLED) display and bright status LEDs for extreme visibility. The gas monitor employs Green, Yellow and Red LEDs to signal normal, fault and alarm conditions.


Stay Connected. Work Smarter.

Bluetooth wireless technology allows you to use your mobile device as an HMI screen and controller. The X/S Connect App is designed with high security standards and provides real-time information to your mobile device. Reduces setup time by at least 50%.

Touch Controls

Our tool-free number.

An industry first, a touch-button interface for an intuitive user experience. The ULTIMA X5000 is completely tool-free, never use a magnet or controller again.


Stands out. But still fits in.

An easy retrofit of the ULTIMA X5000 is possible because it shares the exact mounting footprint as the ULTIMA X, making installation simple using the existing conduit and wiring as well as an integral mounting bracket. Discover the benefits and simplicity of retrofitting and start to save on your operational costs. Learn more here


Simplify Your Maintenance.

Take advantage of remote testing and calibration by deploying the CalGard Remote Calibration Adapter for sensors mounted in difficult to access locations. Our unique solution for these applications allows for accurate sensor calibrations, as the internal bellows mechanism ensures the calibration gas reaches the sensor, rather than escaping and reducing its concentration.
