    Q1: Difference between Gas Detector and Gas Analyzer

    1. Construction
      Gas detectors are generally composed of gas detectors and signal conversion circuits, while analyzers not only have gas detectors and signal conversion circuits, but also a complete set of gas path analysis systems.
    2. Detection methods
      The detection method of gas detectors is often diffusion type, which can only be detected in the air. The gas analyzer takes the collected gas, and then sucks it into the interior for inspection and analysis by rising out of the sampling tube.
    3. Data Accuracy
      The gas detector can only provide qualitative analysis results for the gas. The gas analyzer is an unknown gas concentration, and through the analysis instrument, the gas type and concentration contained in the unknown gas are given.
    4. Measurement purpose
      The detection purpose of the gas detector is mainly for safety protection and preventive detection. The detection of the gas analyzer is mainly for the gas composition and content in the measured environment. The detection accuracy of the gas analyzer is higher than that of the gas detector.
    5. Measurement method
      When the gas detector is used, it is only necessary to place the gas detector in the measured environment and the instrument can display the value and complete the detection. The gas analyzer must introduce gas into the instrument and strictly adjust the technical conditions, such as temperature, pressure, flow rate, etc. Only when the operator adjusts the instrument correctly, can accurate measurement data be obtained.

    Tips: Natural diffusion vs. pump suction gas detectors

    Gas detectors all know that there are two common detection methods, one is natural diffusion, and the other is pump suction. But what is the difference between the two? The natural diffusion type is to slowly sense the gas without applying any external force. The pump suction type uses a self-priming pump to inhale by itself. For example, the human nose responds faster, so it is necessary to choose the right detection method to effectively detect the gas.
