Flammable gas detector (explosive meter)<\/span><\/h2>\n
\n

flammable gas detector<\/span><\/strong>\u00a0(natural gas, LPG, hydrocarbons, solvents, alcohols) constitute the largest part of gas detection. A fixed gas detector for flammable gas can be used in almost every industry: industries with SEVESO or COMAH plants, chemical, petrochemical as well as\u00a0<\/span>gas detection in boiler rooms<\/span>\u00a0in the tertiary sector such as. There are two main monitoring technologies depending on the targeted flammable gas to be detected:<\/span><\/p>\n

    \n
  • catalytic sensor<\/span><\/strong>\u00a0: sensor technology used for almost every flammable gas. This solution is highly efficient for monitoring natural gas, LPG, hydrocarbons, solvents and even some volatile compounds.<\/span><\/li>\n
  • Infrared Sensor<\/span><\/strong>\u00a0: This technology should be preferred for every sector where there is a constant residual presence of flammable gases (refineries, paint or solvent factories, distilleries\u2026).<\/span><\/li>\n<\/ul>\n<\/div>\n

    toxic gas detector<\/span><\/h2>\n
    \n

    As the use and production of highly toxic products in industry becomes stronger, the dangers to goods (explosion risk) and people (poisoning risk) also increase. Explosions and deaths occur every day around the world, reminding us of this problem.<\/span><\/p>\n

    Monitoring toxic gases<\/strong>\u00a0The most commonly used for\u00a0<\/span>sensor technology\u00a0<\/span><\/strong>It is an electrochemical sensor<\/strong>\u00a0.\u00a0This technology, which can be found in a portable or fixed gas detector, provides a large panel of gas detection sensors. For some rare gases that require measurements expressed in ppb (parts per billion), only\u00a0colorimetric paper technology<\/strong>\u00a0will be available.<\/span><\/p>\n<\/div>\n

    Asphyxiating gas detector (lack of oxygen)<\/span><\/h2>\n
    \n

    suffocating gases,<\/span><\/strong>\u00a0It contains many gases with the same properties:\u00a0<\/span>They reduce the oxygen level<\/span><\/strong>\u00a0. In almost every case a\u00a0<\/span>Even if the oxygen gas detector (O2 detector) is sufficient, for example a\u00a0<\/span>CO2 gas detector<\/span>\u00a0It is recommended to use an asphyxiating gas detector when available, such as a (carbon dioxide) or a helium fixed gas detector\u00a0.<\/span><\/p>\n

    • For oxygen and some rare gases\u00a0electrochemical sensor<\/strong><\/span><\/li>\n
    • For carbon dioxide (CO2)\u00a0<\/strong>infrared absorption sensor<\/strong><\/span><\/li>\n
    • For almost any flammable gas that can replace oxygen in case of leakage\u00a0catalytic sensor<\/strong><\/span><\/li>\n<\/ul>\n<\/div>\n

      VOC detector (Volatile Organic Compound)<\/span><\/h2>\n
      \n

      volatile organic compounds<\/span><\/strong>\u00a0(\u00a0<\/span>VOC<\/span>\u00a0) is a large family of gases and gaseous substances that can be polluting, toxic and even carcinogenic. Because they are volatile, they can easily spread into the atmosphere. Therefore, to be protected, they must be detected and measured with a fixed VOC monitor.<\/span><\/p>\n

      VOC explosive mixtures<\/span><\/strong>\u00a0before concentrations reach an explosive level (tens of thousands of parts per million).\u00a0<\/span>they are very toxic<\/span><\/strong>\u00a0.\u00a0In fact, explosiveness levels are set at ten ppm. Various technologies are available for VOC detectors depending on the risk to be monitored:<\/span><\/p>\n

        \n
      • For toxicity detection\u00a0photo-ionization lamp (PID lamp)<\/strong>\u00a0or\u00a0<\/span>semiconductor sensor (expressed in ppm).<\/span><\/strong><\/li>\n
      • Catalytic sensor for explosiveness detection<\/span><\/strong>\u00a0or\u00a0<\/span>infrared absorption\u00a0<\/span><\/strong>sensor<\/span><\/strong>\u00a0(where available) expressed as %LEL.<\/span><\/li>\n<\/ul>\n<\/div>\n

        Refrigerant gas detector (freons)<\/span><\/h2>\n
        \n

        Halogenated hydrocarbons (CFCs and HCFCs), alkenes (HFOs), and almost every refrigerant are regulated under specific legislation that limits (or prohibits) their use. The use of chillers also requires a monitoring system \u2013 usually\u00a0<\/span>a fixed gas detector for freons<\/span>\u00a0. There are two main measurement technologies for Freons:<\/span><\/p>\n

          \n
        • semiconductor sensor<\/span><\/strong>\u00a0: The most commonly used technology for monitoring freons<\/span><\/li>\n
        • Infrared absorption sensor<\/span><\/strong>\u00a0: A very sensitive but very expensive technology used for some freons<\/span><\/li>\n<\/ul>\n

          Gas\u00a0<\/span><\/strong>Detects<\/span><\/strong>\u00a0offers many services for fixed gas detection in certain regions, such as on-site installation, installation, commissioning and calibration of gas detectors.
