Laser dust particle counter is an instrument used to detect the number and size of dust particles in the air. Its main application areas include industries that have strict requirements for air quality, as well as environments and places that require cleanliness. This machine is widely used in the electronics industry, pharmaceutical workshops, semiconductor, optical or precision machining, plastics, painting, pharmaceuticals, environmental protection, inspection institutes and other production enterprises and research departments.
Precautions for using laser dust particle counter:
1. The laser dust particle counter should be used in a clean environment to prevent damage to the laser sensor.
2. The particle counter is mainly used to test the clean environment of the purification workshop. When there are loose particle materials, dust sources and spray in the tested area, it must be kept at least 12 inches away from the inlet pipe. To prevent contamination of sensors and pipelines by the aforementioned particles and liquids.
3. Do not test mixed gases that may cause reactions (such as hydrogen and oxygen). This gas may also cause an explosion inside the counter. To test these gases, it is necessary to contact the manufacturer for more information.
4. Do not sample compressed air without high-pressure pressure reducing equipment (such as high-pressure diffusers), all particle counters are designed to operate at one atmosphere.
5. Water, solution or other liquids cannot enter the sensor through the inlet pipe.
6. When connecting an external printer or an external temperature and humidity sensor, the counter needs to be turned off first; When performing printing operations, there must be printing paper on the printer, otherwise it may damage the print head.
7. When sampling, the gas emitted from the counter itself or contaminated by the gas emitted from the counter is rarely sampled.
8. Do not start the counter when the inlet pipe is covered or blocked.
