[China Instrument Network Instrument R&D] The "Smoke (Gas) Sampler Integrated Calibration System Study" project undertaken by the Hubei Provincial Institute of Metrology and Measurement Technology is progressing smoothly. It has developed soot that covers measurement and inspection items such as pressure, flow, and temperature. (Gas) sampler comprehensive calibration system, the next step will be integrated optimization of the system.
In recent years, with the continuous improvement of the environmental awareness of the entire society, governments at all levels and the general public have paid more attention to haze management and are more sensitive to air quality. Under the high pressure of environmental protection, smart smoke (gas) samplers are becoming more popular in environmental monitoring, labor protection, industrial hygiene, factories and mines, and other industries. They can sample the concentration of particulate matter and harmful gases in pipeline pollution sources and smoke The accuracy of continuous measurement instruments is evaluated and calibrated to provide data and technical evidence for environmental governance.

Because smart smoke (gas) sampler needs to be measured and measured by measurement professionals such as temperature, pressure, flow, and chemistry, the current measurement work still has problems such as low detection efficiency and complicated certificates, which directly affects the smart smoke (gas). Sampler detection accuracy. Dust (gas) emission-related parameters were inaccurately checked, and industrial and construction industry and other key industries' exhaust emission control lost precise data support.
In order to solve the above problems, the Hubei Provincial Metrology Institute formally established the project in September 2015, and launched the “Study of comprehensive verification system for smoke (gas) sampler†project. Over the past year or so, the project team has focused on various types of exhaust gas inspection requirements, combined with measurement expertise requirements, conducted in-depth research on the mechanism of equipment, and unremittingly promoted project research. It has successfully developed a soot (gas) sampler that covers measurement items such as pressure, flow, and temperature. Comprehensive calibration system can realize rapid verification of multiple parameters of the smoke (gas) sampler; At the same time, it introduces advanced ultrasonic flow measurement methods, automatic pressure generation system and dry body furnace temperature measurement system, making the smoke dust sampler integrated measurement more Accurate and fast. In the next stage, the project team will also integrate chemical, flow and other parameters detection items into the system, and optimize the system as a whole to form a highly automated measurement and inspection system.
In the face of increasingly stringent environmental protection requirements, the Hubei Provincial Institute of Metrology will focus on research and development of “smoke (gas) sampler comprehensive calibration system†and focus on strengthening measurement techniques in environmental protection related fields to provide rapid verification of various environmental monitoring instruments. In response, China will provide more powerful technical support for measurement in the field of environmental monitoring and improvement in China's environmental monitoring.
