High-precision gas analysis dynamic calibrator

Abstract

The invention relates to the field of gas detection, in particular to a high-precision gas analysis dynamic calibrator which comprises an external structure, an internal structure playing a gas detection effect is installed in the external structure, and the front end of the external structure is fixedly connected with a control panel used for controlling the calibrator. The bottom end of the external structure is fixedly connected with a rubber pad for damping and anti-falling protection, the surface of the external structure is fixedly connected with a heat dissipation structure for cooling an instrument, the front end of the external structure is fixedly connected with a handle for facilitating lifting, and the rear end of the external structure is fixedly connected with an instrument interface for connecting external equipment. The calibrator automatically calibrates and automatically calibrates the flow controllers so as to reduce errors between the flow controllers and improve the precision of gas distribution concentration, is provided with a multi-channel standard gas interface, does not need to frequently plug and pull pipelines, is convenient and quick, can clean the pipelines and the interiors of the controllers by using diluent gas after gas distribution is finished, and greatly prolongs the service life of an instrument.

Description

technical field [0001] The invention relates to the field of gas detection, in particular to a high-precision gas analysis dynamic calibrator. Background technique [0002] The rapid development of society has brought a huge impact on the environment in which we live. Among them, air pollution is also particularly important. The Air Pollution Index is to identify the quality of the air, and it is the main harmful substances in the air. Sulfur dioxide (SO2), nitrogen The concentrations of the three pollutant indicators (NOx) and inhalable particulate matter (PM10) are compared with the corresponding air quality standards, and various pollution indexes are obtained through mathematical calculations, and the highest one is the current and local air pollution index. Most of the primary pollutants in the air in our city are PM10. PM10 refers to particles with a diameter of less than 10 microns in the air that can be inhaled by the human body. Therefore, an instrument for testing ...

AI Technical Summary

Problems solved by technology

[0004] For the existing gas dynamic calibrator, it needs manual operation to calibrate it, resulting in data difference, increasing the error between the flow controllers, reducing the accuracy of the gas distribution concentration, and after the gas distribution is completed, the internal pipe of the equipment Some gas will remain in the circuit, which will affect the service life of the instrument. Secondly, the equipment is a single set of standard gas interface, which will cause inconvenience in operation and is troublesome to use.
