DEX-14/N Ex

Device model: DEX-14/N
Device type: DEX/F

Detectors DEX®/F are used for continuous monitoring of premises for combustible and toxic gases (and oxygen). The detectors come with two preset concentration thresholds for alarm purposes.

Detector DEX®/F can be used in all places specified as II 2 G (according Directive 94/9/EC - ATEX). All detectors are made according to Polish and European Standards PN-EN 60079-0:2006(U) and PN-EN 60079-1:2008.


  • detachable and interchangeable sensor unit guarantees easy maintenance and low cost operation;
  • easy change of detection gas or calibration of detector;
  • built in temperature compensation;
  • semiconductor or catalytic or infra-red sensor for combustible gases or electrochemical sensor for toxic gases or oxygen;
  • high temperature (up to +80°C) version available;
  • all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).
