The laser dust particle counter is used as the "ceiling" for environmental control analysis, and these use safety should not be ignored

The main application of the laser dust particle counter is the principle of light scattering. When counting and measuring, a photomultiplier tube is used to receive the light reflected by the dust particles to measure the size and quantity, and analyze, accumulate and digitally display. With the rapid development of electronic technology and environmental control technology, dust particle counters have been widely used in environmental control analysis and have become an indispensable key device in the current environmental control technology field. More and more enterprises need to apply clean technology to control safety and health.

Laser Dust Particle Counter

Notes on using laser dust particle counter:
1. When the inlet pipe is covered or blocked, the counter cannot be started
2. The laser dust particle counter should be used in a clean environment to prevent damage to the laser sensor
3. Mixed gases (such as hydrogen and oxygen) that may produce reactions cannot be measured. This gas may also explode inside the counter. Testing these gases requires contacting the manufacturer for more information.
4. The sample compressed air cannot be obtained without high pressure decompression equipment (such as a high pressure diffuser), and all particle counters are designed to operate at one atmospheric pressure.
5. Water, solutions or other liquids cannot enter the sensor from the inlet pipe.
6. 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 places in the measurement place, it must be kept at least twelve inches away from the inlet pipe. In order to prevent the above particles and liquid from contaminating the sensor and pipeline.
7. When taking samples, avoid taking the gas discharged from the counter itself or polluted by the gas from the counter.
8. When connecting an external printer or an external temperature and humidity sensor, you need to turn off the counter first; when performing printing operations, there must be printing paper on the printer, otherwise the print head will be damaged.

Laser Particle Counter (Dust Particle Counter) - Laser Safety:
1. AEROTRAK 9303 handheld laser particle counter is a Class I laser instrument.
2. During normal use, personnel should avoid the laser irradiation range.
3. Take precautions to avoid exposure to highly focused invisible light harmful radiation.
4. Exposure to this light may cause blindness.

Laser Particle Counter (Dust Particle Counter) - Precautions:
1. Do not remove any part of the particle counter unless explicitly stated in this manual.
2. Do not remove the case or cover.
WARNING: Use of controls, adjustments or other procedures other than those specified in this manual may result in exposure to harmful optical radiation.
