Particle counters and how to make your particle counters last longer - HUAWEI

Various Models

Particle Counter

Although different models may vary in functionality and interface, the basic operation is generally similar:

1. Turn on the power to allow the device to warm up.

2. Set the working parameters. If no changes are needed, you can skip this step. For detailed button operations, refer to the product manual of each specific instrument. Note that settings will not take effect during sampling.

3. After completing the setup, start the sampling process and read the data.

4. Connect a printer to export and print the data. Some devices come with built-in printers for direct printing.

General Tips

Particle Counter

Particle counters can be quite expensive, especially imported models. Proper maintenance and careful use are essential. Here are some important usage considerations:

1. Do not start the counter if the inlet tube is covered or blocked.

2. Use the device in a clean environment to protect the laser sensor from damage.

3. Avoid sampling gases containing oil or corrosive substances, and do not measure mixed gases (such as hydrogen and oxygen) that could react or even explode inside the device. Contact the manufacturer for guidance if testing such gases.

4. Do not use high-pressure decompression equipment like pressure diffusers when sampling compressed air. All particle counters are designed to operate at atmospheric pressure. Ensure that the instrument's position and sampling port are in the same air pressure, temperature, and humidity conditions to maintain normal operation.

5. Prevent water, liquid, or other substances from entering the sensor through the inlet tube.

6. Particle counter

It is primarily used to test the cleanliness of purification workshops. When measuring materials that produce loose particles, dust, or spray, keep them at least 12 inches away from the inlet pipe to avoid contaminating the sensor and piping with particles or liquids.

7. Avoid sampling gas that has been discharged from the counter itself, as it may be contaminated.

8. Before connecting an external printer or a temperature/humidity sensor, turn off the particle counter. Also, ensure the printer has paper before printing, as running out of paper can damage the print head.

9. Handle the device carefully, avoiding excessive vibration or impact. This is especially important for desktop models, where internal components can be easily damaged.
