Concentration-measuring gas detectors DG/P
Concentration measurement and detection devices for toxic and combustible gases (also oxygen and Freon HFC) with splash-proof construction
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).
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).
Features
- 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).

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.
