Device group: Concentration-measuring gas detectors
Device type: DEX/P
Device model: DEX-P7

Detector DEX®/P is used for continuous monitoring of dangerous concentrations of combustible and toxic gases (and oxygen) in places of work and living.

Detector DEX®/P can be used in all places specified as II 2 G (according to Directive 94/9/EC - ATEX). All detectors are made according to European Standards EN 60079-0:2012 + A11:2013, EN 60079-1:2007, EN 60079-1:2014.

All DEX/P are equipped with individual production certificate and calibration certificate.


  • 4-20mA standard analog output (passive);
  • easily interchangeable sensor unit and easy maintenance;
  • easy change of detected gas or calibration of the detector;
  • built-in temperature compensation;
  • catalytic or infra-red sensor for combustible gases or electrochemical sensor for toxic gases or oxygen;
  • sensor unit with “zero” and “span” regulation (calibration outside the detector);
  • low-cost operation;
  • easy fit to existing systems with 4-20mA standard inputs (using MDPL1 limiter);
  • 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).
