Threshold gas detectors DG/F

Detectors DG/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.

DG/F detectors are designed to work only with:

DG/F detectors cannot be used in hazardous locations (according to ATEX Directive).

Features

  • two thresholds set at manufacturing stage;
  • semiconductor sensor for combustible gases or electrochemical sensor for toxic gases or oxygen;
  • easily exchangeable sensor unit for straightforward maintenance;
  • easy change of detected gas and easy calibration (all available DG/F sensor units ready to operate in each DG/F detector);
  • intelligent sensors with build-in TWA and STEL measurement, alarm history, recommended calibration time mark signal;
  • built-in temperature compensation;
  • low cost operation;
  • long time operation (typically 10 years for semiconductor sensors);
  • all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).
