Read： 309 Time：7months ago Source：Transform the World with Simplicity

Dust sampler is an instrument used to collect suspended particles in the air, which is widely used in industrial production, environmental monitoring and other fields. The correct use of dust sampler for sampling is essential to ensure the accuracy and reliability of the sampling data. The following will introduce the dust sampler sampling precautions and operating procedures to help users standardize operations and improve sampling efficiency.
2. Select appropriate sampling head and sampling time according to sampling requirements to avoid too long or too short sampling time;
3. Select appropriate sampling place according to the air pollution situation on site to avoid interference factors such as tuyeres and vents.

2. sampling operation
1. Place the dust sampler in a stable position to avoid vibration or tilt;
2. Turn on the dust sampler, set the sampling parameters according to the operation manual, and ensure that the parameters are set correctly;
3. Avoid human interference or operation errors during the sampling process, and keep the sampling instrument running stably;
4. Turn off the dust sampler in time after sampling, and record the sampling time, location and other relevant information.

3. sampling post-treatment
1. Take down the sampling head, clean it with clean solvent and dry it;
2. Calibrate and maintain the dust sampler to ensure the normal operation of the instrument;
3. Organize and record the sampling data, and report or save it in time.

above is the dust sampler sampling matters needing attention and operating procedures in detail, hoping to help users to correct and efficient sampling work. When using the dust sampler, be sure to operate in strict accordance with the operating procedures to ensure the accuracy and reliability of the sampling data, and provide strong support for related work.
