Operation and maintenance skills of light scattering particle monitoring instrument
Date: 2025-08-11Read: 0
Light scattering particle monitoringInstruments are important equipment in the field of environmental monitoring, and standardized operation and scientific maintenance are crucial to ensuring the accuracy of monitoring data. 
1、 Operation points
Before use, it is necessary to check whether the power connection of the instrument is stable to ensure normal power supply. After startup, zero calibration should be performed to establish a reliable benchmark reference. The sampling inlet should be kept unobstructed to avoid obstruction or contamination that may affect the airflow. Set appropriate sampling intervals and data recording frequencies based on the characteristics of the monitoring environment. Regularly clean the sampling filter to prevent particle accumulation from affecting airflow stability. During the operation of the instrument, maintain a relatively stable temperature and humidity environment to avoid interference from special conditions during measurement. Operators need to undergo professional training and be familiar with the instrument interface functions and basic operating procedures. The selection of monitoring points should be representative and avoid being close to local pollution sources or ventilation openings.
2、 Daily maintenance skills
Check the sampling system for residual particulate matter after daily use and clean it if necessary. Clean and maintain the optical path system weekly to ensure that the surface of the optical components is free of dust pollution. Check the calibration status monthly and use standard particulate matter for multi-point calibration if necessary. Regularly check the operation status of the fan and airflow system to ensure stable sampling flow. When the instrument is not in use for a long time, the power should be disconnected, the internal components should be cleaned, and stored properly. Maintenance operations should be carried out in a clean environment to avoid introducing new sources of pollution. Establish detailed maintenance logs to record the content of each maintenance and changes in instrument status.
3、 Precautions
Avoid using instruments in strong electromagnetic interference environments to prevent signal abnormalities. The sampling tube should be replaced regularly to prevent aging from affecting the efficiency of airflow transmission. If the optical window is contaminated, it should be treated with specialized cleaning tools to avoid scratches. When encountering abnormal data, the instrument status should be checked first rather than directly adjusting parameters. During transportation, original packaging materials should be used to prevent severe vibration from damaging precision components. Regularly backup monitoring data to prevent accidental loss of important environmental information.
Through standardized operation and scientific maintenance,Light scattering particle monitoringThe instrument can operate stably for a long time, providing reliable data support for environmental air quality assessment and assisting in ecological environment protection work.
