  • Description
  • Specifications

Portable Gas Detector of 4 or 5 gas types. The “Corundum” is used for automatic monitoring of the air in the working area in order to ensure the industrial safety of facilities, and during emergency rescue operations, including during the emergencies management.


  • Automatic detection, identification, and control over the exceeding of the threshold concentrations of up to five gas types simultaneously, including hazardous chemicals, oxygen, hydrogen, carbon dioxide, organic substances, and combustible gases;
  • Displaying data on the measured component concentrations, exceeding of the threshold concentration values and monitoring data, on the display;
  • Viewing the IMS parameters (type of a measured gas, expiration date, recommended date of the next verification, and the values of the thresholds pre-set);
  • Calculation of the weighted average concentration value for each of the measured components;
  • Possibility of a “hot” replacement of the IMS;
  • Archiving data on the measurement and the exceeding of the thresholds, in non-volatile memory;
  • Sound and light alarm when the concentration values thresholds of measured components are exceeded;
  • Automatic failure diagnostics, ISM resource control;
  • Transfer archive data to a PC.
