FAQs

Q1: What is a fixed gas detector?
A1:
The fixed gas detector is composed of sensors and transmitters, and is installed at the detection site. The secondary instrument consisting of circuit, power supply and display and alarm device is installed in a safe place, which is convenient for staff to monitor. In industrial installations and production processes, fixed gas detectors are generally used, because fixed gas detectors can be installed at specific detection points to detect specific gas leaks.

Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.

Q3: Difference between fixed gas detector and portable gas detector
A3: The biggest advantage of fixed gas detectors is 24-hour uninterrupted measurement. As long as the power is turned on, the fixed gas detector is in normal detection work. Portable gas detectors are usually used in confined spaces and confined spaces, but the gas environment in these spaces is usually very complex, and there will be situations such as lack of oxygen and high concentrations of harmful gases.

Tips: How to maintain a fixed gas detector?

  • The fixed gas detector should be calibrated and tested regularly.
    When replacing a fixed gas detector probe, in addition to a certain sensor activation time, the instrument must also be recalibrated. In addition, use standard gas for response detection before using the fixed gas detector to ensure the protection of the instrument.
  • Watch out for interference between other sensors and the fixed gas detector.
    The fixed gas detector is not suitable for any combination of toxic and harmful gases. Generally speaking, each gas detector corresponds to a specific detection gas, but no gas detector can be absolutely effective.
  • Note the lifetime of the fixed gas detector.
    A fixed gas detector has a certain lifespan. In general, LEL sensors have a longer lifespan and can generally be used for about three years. Photoionization detectors have a lifespan of four years or more. Electrochemical specific gas detectors have a relatively short lifespan, typically 1 to 2 years. Oxygen sensors have a shorter lifespan, about a year or so.
