  • Description
  • Specifications

Used for continuous automatic monitoring of air as:

  • an RCC subsystem as part of the OKSION (All-Russian Integrated Public Notification and Warning System) and SZIONT (Integrated Public Transport CCTV, Environmental Monitoring and Emergency PA System);
  • autonomous means of radiation and chemical survey as part of mobile systems;
  • detector in ventilation control systems to prevent the entry of hazardous chemicals and toxic agents into ventilated rooms.
Used by units of the EMERCOM of Russia and other law enforcement agencies


  • automatic detection, identification, and simultaneous control over exceeding threshold concentrations of up to 6 hazardous chemicals and toxic agents in the air of the working area;
  • automatic detection of excess gamma background levels;
  • automatic control of external actuators when signal thresholds are exceeded for hazardous chemicals and toxic agents and radiation background;
  • indication of the concentrations of measured components on the display (optional);
  • archiving measurement data and threshold exceeded in non-volatile memory;
  • sound and light alarm when threshold concentration values of measured components are exceeded;
  • transfer of information on measured parameters and archive data to a remote PC or to a local network.

Application Area:

  • transport infrastructure facilities (subway, railway stations and terminals, bus stations, airports, etc.);
  • government facilities, buildings, and structures;
  • healthcare institutions;
  • business centres and office buildings;
  • shopping and entertainment complexes, sports facilities and structures, crowded places, etc.;
  • cultural and sports facilities and structures.
