    Tips: How to Select a Gas Detector?

    1. Gas type and concentration
    If the majority of components are methane and other less toxic alkanes, LEL detector is undoubtedly the most appropriate.
    If there are toxic gases such as carbon monoxide and hydrogen sulfide, it is prior to select a specific gas detector, to ensure the safety of workers.
    If the majorities are the organic, toxic and harmful gases, such as aromatic hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, lipids, a photoionization detector shall be selected.

    2. Applications
    The selection of gas detector differs from the industrial environments.

    • Fixed gas detector
      Such a gas detector is mostly used in industrial devices and production processes. It can be installed on a specific detection point to detect specific gas leaks.
    • Portable gas detector
      As the portable instrument is easy to operate and compact, it can be carried to different production sites.
      In open occasion like open workshops for security alarm, a wearable diffusion-type gas detector is recommended because it can display the concentration of toxic and harmful gases continuously, real-time and accurately on site.
      If it’s used in a confined space, such as the reaction tank, storage tank or container, sewer or other underground pipe line, underground installations, cargo hold and tunnel, a multi gas detector with a built-in sampling pump is recommended.
