Device group: Concentration-measuring gas detectors
Device type: DG/P

Detectors DG/P are used for continuous monitoring of premises for combustible and toxic gases. The detector performs cyclic measurement of gas concentration in the air and transmits the measured value in 4-20mA standard (passive output).

DG/P detectors are designed to work with:

For use with control units from other manufacturers, GAZEX recommends to use detectors type DG/PV with dual outputs (active 4-20mA and 2-10V).


  • 4-20mA standard analog output (passive);
  • easily exchangeable sensor unit and easy maintenance;
  • easy change of the detected gas or calibration of the detector;
  • built-in temperature compensation;
  • 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;
  • all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).
