Dust particle counterIt is an instrument used to measure the number and particle size distribution of dust particles per unit volume in clean environments. It can be widely used for institutions such as drug testing 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 institutes, and scientific research departments in various provinces and cities.
Dust particle counterNowadays, many clean industries such as biopharmaceuticals, food processing, and microelectronics manufacturing have high requirements for the cleanliness of their production cleanrooms. Therefore, these industries use dust particle counters in their production workshops to measure the cleanliness of the production workshop. So, what precautions should be taken in the daily use of dust particle counters?
1. Do not start the dust particle counter when the inlet pipe is covered or blocked;
2. It should be used in a clean environment to prevent damage to the laser sensor;
3. Do not extract gases containing oil stains or corrosive substances, and do not test mixed gases that may cause reactions (such as hydrogen and oxygen). These gases may also cause explosions inside the counter. If measuring these gases, it is necessary to obtain more information from the manufacturer before proceeding with the operation;
4. Do not sample compressed air without high-pressure pressure reducing equipment (such as high-pressure diffusers), all counters are designed to operate at one atmosphere. The working position and sampling port of the instrument should be in the same pressure and temperature and humidity environment to ensure the normal operation of the instrument;
5. Water solution or other liquids cannot enter the sensor through the inlet pipe, etc.
