DEX/P

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.

Features

  • 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).

Detection of substance/property in other areas or other substances/properties is possible = special execution, requires consultation.
In special cases, it is possible to select the detector parameters for a specific application = required analysis of the conditions of use.
