Relevant requirements when using a dust particle counter The particle counter was developed by microscope, and it has undergone the processes of microscope, settling tube, sedimentation instrument, centrifugal sedimentation instrument, particle counter , laser air particle counter , PCS nano laser air particle counter . The laser air particle counter test is fast and dynamic. Wide-ranging, unaffected by human factors and other advantages, and become an advantage product in many industries. Can be widely used in various provinces and municipal drug inspection institutes, blood centers, epidemic prevention stations, disease control centers, quality supervision institutes, electronics industry, pharmaceutical workshops, semiconductor, optical or precision machining, plastics, painting, hospitals, environmental protection, inspection Such as production companies and scientific research departments. The relevant requirements when using the dust particle counter are as follows:
Nutritional supplements, also known as nutritional supplements, nutrients, dietary supplements, etc., are used as an auxiliary means of diet to supplement the amino acids, trace elements, Vitamins, minerals, etc. required by the human body. Nutritional supplements can be composed of amino acids, polyunsaturated fatty acids, minerals and vitamins, or only one or more vitamins, or one or more dietary ingredients, except for amino acids, vitamins, minerals In addition to nutrients such as substances, it can also be composed of herbs or other plant components, or concentrates, extracts or compositions of the above components.
Unlike fortifiers, dietary supplements are not integrated with food. Most of them are pills, tablets, capsules, tablets, or oral liquids that are taken separately with meals.Nutrient supplements are not regular foods, nor are they food fortifiers.Nutritional supplements can be composed of amino acids, fatty acids, minerals and vitamins, or only consists of one or a variety of vitamins, can also be composed of one or more dietary ingredients, in addition to including amino acids, vitamins, minerals and other nutrients, also can have herbs or other plant components, or more ingredients of concentrate, extract or combination.

1. 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 may also explode in the counter, if the gas is measured with the manufacturer, obtain more information and then operate;
2. When handling, it should be handled lightly and with less vibration and impact. Especially for desktop particle counters, be more careful to avoid damage to internal components;
3. 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;
4. When connecting an external printer or connecting an external temperature and humidity sensor, you need to turn off the counter first; when performing the printing operation, the printer must have printing paper, otherwise it will damage the print head;
5. When the inlet pipe is covered or blocked, do not start the dust particle counter;
6. The particle counter is mainly used to test the clean environment of the purification workshop. When the measured area 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 pipeline with the above particles and liquids;
7. When sampling, avoid sampling the gas contaminated by the gas discharged from the counter itself;
8, should be used in a clean environment to prevent damage to the laser sensor;
9. An aqueous solution or other liquid cannot enter the sensor from the inlet tube.
