What are the differences between a gas detector and a gas analyzer?
In life, we often combine gas detector and gas analyzer. It is wrong to think that it is the same instrument and the same function. The detection purpose of gas detector is mainly used for safety protection, and the detection purpose of gas analyzer is mainly to analyze the gas composition and content in the tested environment. Besides these misunderstandings, what are the differences between gas detector and gas analyzer?
First, the structure is different:
Gas detector is generally composed of gas detector and signal conversion circuit, while analyzer not only has gas detector and signal conversion circuit, but also has a set of gas path analysis system.
Second, the detection methods are different:
The detection method of gas detector is often diffusion type, which can only be detected in air. The gas analyzer sucks the collected gas into the interior for inspection and analysis by rising out of the sampling tube.
Third, the accuracy of the data is different:
The gas detector can only provide qualitative analysis results for the specified 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.
Fourth, the purpose of measurement is different.
The detection purpose of the gas detector is mainly used for safety protection, and different gas detectors are set corresponding to the gas components in the detection environment, so as to achieve the function of preventive detection. The detection purpose of gas analyzer is mainly to detect the gas composition and content in the tested environment, and the detection accuracy of gas analyzer is higher than that of gas detector.
Five, complete the whole process of determination of different operating methods.
When the gas detector is used, it only needs to be placed in the tested environment to display the numerical value and complete the detection.
The gas analyzer must introduce gas into the instrument and strictly adjust the technical conditions, such as temperature, pressure and flow rate. Only when the operator adjusts the instrument until a stable chemical process is realized can accurate measurement data be obtained.
According to the above summary, there are five differences between gas detector and gas analyzer.
