Precautions for applying the dust particle counter (Part 2)
Note on the application of dust particle counters:
1) When the inlet tube is covered or blocked, do not start the counter. The laser dust particle counter should be used in a clean environment to prevent damage to the laser sensor.
2) Do not measure mixed gases (such as hydrogen and oxygen) that may react. This gas may also explode inside the counter. These gases need to be measured with the manufacturer for more information.
3) Water, solution or other liquids cannot enter the sensor from the inlet tube. The particle counter is mainly used to test the clean environment of the purification workshop. When there is loose material, dust source and spray at the place where it is measured, 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.
4) At the time of sampling, the gas contaminated by the gas discharged from the counter itself or by the counter is sampled. When connecting an external printer or connecting an external temperature and humidity sensor, you need to turn off the counter first; when performing a printing operation, the printer must have printing paper, otherwise the print head will be damaged.
5) Do not sample compressed air without high pressure decompression equipment (such as high pressure diffusers). All particle counters are designed to operate at one atmosphere.
