Preparation

Remove the dust particle testing instrument and sampling head from the packaging box for the cleanroom.

Operate

Connect the filter to the intake.

2. Turn on the power switch on the side of the instrument. The screen displays 0.3um. If the screen does not show, please check if the battery needs to be charged.

3. During each test, calibrate the equipment, connect the supplied 0.2um filter to the intake, and then start. The filtered clean air will clean the equipment, with particles ≥20.3um being cleaned.

After calibration, replace the sampling head, and then press the buttons to sequentially select 0.5um and 5.0um test particle sizes.

5. After selecting the test particle size, press the button to initiate the test. You will hear the sound of the built-in air pump running. After 6 seconds, the screen will display a number greater than or equal to the selected particle size, and the instrument will continue to re-measure.

After 9 tests, the screen displays the average of 10 readings in 1 minute, recording the data results.

6. If the next object is detected, repeat steps 4 and 5.

End

After the test, disconnect the power, remove the sampling head, and place it in the instrument box.

2. Arrange the air particle counter for e gas and place it into the instrument.

Four: Cautionary Notes

Do not initiate the counter as the inlet pipe is covered or blocked.

Counters should be used in a clean environment to prevent damage to the laser sensors.

The counter is primarily used to test the cleanliness of a purification room. When measuring areas with loose particles, dust sources, and spray points, maintain a distance of at least 12 inches from the intake pipe. Avoid the contamination of sensors and pipes by the aforementioned particles and liquids.

4. Avoid sampling gas that may be contaminated by gas emitted from or by the counter itself during the sampling process.
