Particle counter operation method and precautions for use

Particle counter is a special instrument for testing the particle size and distribution of airborne dust particles. It has the advantages of stable performance, flexible use and high reliability. It is widely used in plastics, painting, hospitals, environmental protection, inspection institutes and other production enterprises and scientific research departments. . Today Xiaobian mainly introduces the particle counter operation method and precautions, I hope to help everyone.

Particle counter operation method and precautions for use

Particle counter operation method

Different types of particle counters have some differences in terms of function and operation interface, but the basic operation steps are similar:

1. Turn on the power to warm up.

2. Set the working parameters. If you don't need to change it, you can skip it. The specific button operation refers to the product introduction of each instrument. Note that the setting is invalid in the sampling state.

3. After the setting is completed, you can start sampling and reading and read the data.

4. Connect the printer, export and print the data, and some products with built-in printer can print directly.

Particle counter operation method and precautions for use

Particle counter usage precautions

1. Do not start the counter when the inlet tube is covered or blocked.

2, should be used in a clean environment to prevent damage to the laser sensor

3. It is forbidden to extract gases containing oily and corrosive substances, and do not measure mixed gases (such as hydrogen and oxygen) that may react. These gases can also explode inside the counter. To test these gases, contact the manufacturer for more information.

4. No high pressure decompression equipment (such as high pressure diffuser) should not sample compressed air. All counters are designed to operate at one atmosphere. The working position and sampling port of the instrument should be in the same air pressure and the same temperature and humidity environment to ensure the normal operation of the instrument.

5. Water, solution or other liquids cannot enter the sensor from the inlet tube.

6. The particle counter is mainly used to test the clean environment of the purification workshop. When the measured material has loose particle material, dust source and spray, it must be kept at least twelve inches away from the inlet pipe. In order to avoid contamination of the sensor and piping with the above particles and liquids.

7. When sampling, avoid sampling the gas contaminated by the gas discharged from the counter itself.

8. When connecting an external printer or connecting an external temperature and humidity sensor, first turn off the counter; when performing the printing operation, the printer must have printing paper, otherwise the print head will be damaged.

9. When handling, it should be handled lightly and with less vibration and impact. Especially for desktop particle counters, be careful not to damage internal components.
