Description

technical field [0001] The invention relates to gas or liquid analysis, in particular to an immersion type fluid analysis equipment and a debugging method thereof. Background technique [0002] With the development of society and the improvement of living standards, people pay more and more attention to their own living environment, and gradually increase their attention to the quality of air, drinking, food, etc. As a high-precision, fast, and low-power analysis technology, spectral analysis technology, such as absorption spectrum analysis technology, can be widely used in continuous analysis of flue gas and water quality. [0003] In flue gas analysis, sampling method and in-situ method are usually used. Among them, the analysis process of the sampling method is as follows: the flue gas to be measured in the flue is sampled by an air pump, and then sent into the heated gas chamber, the light emitted by the light source passes through the flue gas to be measured in the flu...
