DG/F

DG/F

Threshold detectors of toxic and combustible gases (also oxygen and Freon HFC) with splash-proof construction

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.

Detector DG/F 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).

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.
