The Xgard range is a comprehensive selection of fixed multi gas detectors that meet the diverse requirements for gas detection globally. Whether you need gas detection around water treatment facilities, oil and gas, power, research facility or manufacturing installations, with three different sensors to choose from, there will be an Xgard to suit your needs.
Xgard offers three different sensor concepts so you can choose exactly what you need for your site. Xgard is available in flameproof, intrinsically safe, or safe area formats for use in all environments, whatever the classification.
The Xgard range offers a comprehensive selection of fixed point gas detectors that meet the diverse requirements for flammable and toxic gas detection and oxygen monitoring in industries throughout the world.
Whichever version of the Xgard you choose, you can be confident that they’re all designed to operate in even the harshest conditions, and can be manufactured using materials which can withstand the conditions of your specific space.
With flexible installation options, the Xgard series can be either wall or ceiling mounted, without the need for additional brackets. Designed for easy installation, the replacement of sensors and sinters is extremely simple all helping to keep maintenance costs down.
