Background：

The gas detection alarm instrument uses the probe to be directly exposed to the measured air or sample gas environment for detection. The gas analyzer is to introduce the measured gas (sample gas) into the instrument through a special method for measurement. Then lead to the outside of the instrument to vent. The structure of the gas detection alarm is relatively simple. Only the probe (sensor) and the sensor signal conversion circuit part are included. The gas analyzer is not only equipped with probes (sensors) but also a complete set of gas circuit systems. That is to introduce the sample gas into the instrument, and then lead out a complete gas circuit system for the instrument to be vented or recovered.

Differences in how to operate：

When the gas detection alarm instrument is used, it only needs to place the instrument in the atmosphere to be measured. The instrument displays the value. In a gas analyzer, the sample gas must be carefully introduced into the instrument. Then carry out strict adjustment of process and technical conditions. Such as temperature, pressure, flow, etc. Only after the operator adjusts the instrument until a stable chemical process is achieved. to obtain accurate measurement data. The data obtained before this time is incorrect and must be discarded.

Difference in accuracy：

The gas detection alarm can only provide qualitative analysis results and relatively rough quantitative analysis data. The data displayed by this instrument do not stand up to scrutiny. Error analysis cannot be performed (since "error" can only be talked about when the analysis data deviates very little from the true value). Therefore, it cannot be used as accurate analytical data at all to determine (decide) measures for important process improvement adjustments. The gas analyzer is a strict measuring instrument.

During quantitative analysis, it can provide very accurate data C. This data can be used as the basis for the improvement and improvement of gas production and safety production. Use it to guide and carry out production management, quality management and enterprise management. Even, this kind of data can be used as an important basis for judicial criminal investigation work. Use it to fight lawsuits and determine the boundaries of right and wrong.
