Problems solved by technology
[0003] The cost of standard gas prepared by professional manufacturers is very high, which is very uneconomical and causes a lot of waste
In addition, it is often difficult to obtain an accurate nominal value when preparing a static standard gas, which brings certain difficulties to the calibration work
This is especially true when calibrating multi-component gas monitoring systems

Description
technical field [0001] The invention relates to the detection field, in particular to an intelligent gas distribution system for online detection. Background technique [0002] Standard gas, as the measurement standard of gas composition, has been widely used in scientific research, atmospheric environment monitoring, calibration of instruments and meters, inspection of chemical products and other fields, especially in the field of gas monitoring. Standard gas is an inspection and monitoring method, analytical instrument , Monitoring instrument technology and an important basis for quality control. [0003] The cost of standard gas prepared by professional manufacturers is very high, which is very uneconomical and causes a lot of waste. In addition, when preparing static standard gases, it is often difficult to obtain an accurate nominal value, which brings certain difficulties to the calibration work. This is especially true when calibrating multi-component gas monitoring...
