At present, in many working environments, it is necessary to install an online particle counter to monitor the particle size and distribution of air dust particles in the clean room, so as to always maintain the number of suspended particles in the environment Within the lower range required by the standard. Therefore, in order to ensure that the working environment of the clean room can meet the relevant requirements, we need to pay attention to some relevant aspects in the process of using the online particle counter. So do you know what to pay attention to when using online particle counters ? The following is a brief introduction by yi yun Tian:

Pay attention to the following when using online particle counters:

1. When the inlet pipe is covered or blocked, do not start the online particle counter.

2. The laser dust collector should be used in a clean environment to prevent damage to the laser sensor.

3. It is forbidden to extract gases containing oil and corrosive substances, and do not measure mixed gases (such as hydrogen and oxygen) that may react.These gases may also produce an explosion in the counter, the measurement of these gases need to contact the manufacturer for more information.

4. Do not sample compressed air without a high-pressure decompression device (such as a high-pressure diffuser). All on-line particle counters are designed to operate in the 1 atmosphere.

5. Water, solution or other liquids cannot enter the sensor from the water inlet pipe.

6. The online particle counter is mainly used to test the clean environment of the purification workshop. If there are loose particles, dust sources and spray at the test location, they must be at least 12 inches away from the water inlet pipe. To prevent the above particles and liquids from contaminating the sensor and piping.

7. When sampling, please avoid sampling the gas emitted from the online particle counter itself or contaminated by the gas generated by the counter.

8. When connecting an external printer or an external temperature and humidity sensor, the online particle counter must be turned off; otherwise, the online particle counter must be turned off. When printing, there must be paper on the printer, otherwise the print head will be damaged.

In summary, it is the precautions for the use of online particle counters. In addition, it is worth noting that before we use the online particle counter, we should actually read the safety instructions in detail. As long as we read the user manual completely, we can obtain more detailed information, so as to better prevent improper operation, which leads to inaccurate test results or adverse effects on the online particle counter itself.
