DK-nn

Household gas detectors type DK-nn are used for continuous monitoring of combustible gases, carbon monoxide or freon gases in residential and ancillary rooms, endangered by their leakage.

Detection of dangerous gas concentration is signalled by activation of optical and acoustic alarm signalling and appropriate alarm control outputs activation. The detectors are equipped with a replaceable sensor module, which guarantees simple and cheap operation.

Area of application

  • oil or gas-fired boiler plants (with boilers without flue gas flow sensor);
  • kitchens and bathrooms equipped with gas appliances e.g. cookers, ovens, water heaters (with open combustion chamber);
  • rooms containing gas appliances such as: valves, gas meters, cylinders, tanks, gas pipes (basements, corridors);
  • rooms with a fireplace, or coal or wood-burning stoves;
  • rooms heated by portable propane-butane stoves;
  • domestic garages;
  • solid fuel-fired boiler rooms;
  • school laboratories;
  • rooms with air conditioning or refrigeration equipment (freon leaks).

Features

  • microprocessor-controlled;
  • external siren control;
  • can work with many devices;
  • the detectors are covered by a 3-year warranty;
  • all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 standard (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.
