What is the difference between a gas detector and a gas analyzer?
In life, we often integrate gas detectors and gas analyzers together. We think that it is the same instrument and the same function, but what we understand is wrong. The detection purpose of the gas detector is mainly for safety protection, and the detection purpose of the gas analyzer is mainly to analyze the gas composition and content in the measured environment. In addition to these essential misunderstandings, the difference between a gas detector and a gas analyzer is also Which are there?
First, the structure is different:
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.
Second, the detection methods are different:
The detection method of the gas detector is often a 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 by lifting out of the sampling tube, so as to analyze it.
Third, the accuracy of the data is different:
Gas detectors can only provide qualitative analysis results for specified gases. 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. The purpose of measurement is different
The detection purpose of the gas detector is mainly for safety protection, and different gas detectors are set corresponding to the known gas components in the detection environment to achieve the role of preventive detection. The detection purpose of the gas analyzer is mainly to detect 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. The operation methods to complete the whole process of determination are different
When the gas detector is applied, it is only necessary to place the gas detector in the measured environment and the instrument can display the value to complete the detection.
The gas analyzer must introduce gas into the instrument, and carry out strict adjustment of process technical conditions, such as temperature, pressure, flow rate, etc. Only when the operator adjusts the instrument until a stable chemical process is achieved, can accurate measurement data be obtained.
