Precautions for using a laser dust particle counter and laser safety
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. It is not possible to measure a mixture of gases (such as hydrogen and oxygen) that may cause a reaction. This gas may also explode inside the counter. To measure these gases, contact the manufacturer for more information.
4. No high pressure decompression equipment (such as high pressure diffuser) can not obtain sample compressed air. All particle counters are designed to operate at one atmosphere.
5. Water, solution or other liquids cannot enter the sensor from the inlet tube.
6. The particle counter is mainly used to test the clean environment of the purification workshop. When the measured material 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 piping with the above particles and liquids.
7. When obtaining the sample, the gas contaminated by the gas discharged from the counter itself or by the counter is obtained.
8. 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 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 strong radiation from invisible light.
4. Exposure to this light can cause blindness.
Laser particle counter (dust particle counter) - preventive measures:
Do not remove any parts of the particle counter unless explicitly stated in this manual.
Do not remove the outer casing or cover.
WARNING: Use of controls, adjustments, or other procedures other than those specified in this manual may result in exposure to harmful light.
