A portable desktop laser particle counter for clean rooms is a device used to monitor particulate matter in the air, widely used in industries such as pharmaceuticals, electronics, food, aerospace, and healthcare. The following is an application analysis of the device.
1、 Basic principles
The laser particle counter irradiates particles in the air with a laser beam, and when the particles pass through the laser beam, scattered light is generated. The photodetector in the device captures these scattered lights and determines the size and quantity of particles based on the intensity and frequency of the scattered light. Through this method, laser particle counters can monitor particles of different diameter ranges in the air in real time.
2、 Main functions
Particle counting and classification
Classify particles based on their size (e.g. 0.3 μ m, 0.5 μ m, 1 μ m, etc.) and provide particle counting data.
real-time monitoring
Real time display of particulate matter concentration in the cleanroom to ensure that the environment meets regulatory standards.
Data recording and analysis
It has data storage and export functions, which facilitate subsequent data analysis and report generation.
alarm function
When the particle concentration exceeds the set threshold, the equipment can issue an alarm to remind the operator to take measures.
3、 Application Fields
pharmaceutical industry
In the process of drug production, the air quality in the clean room directly affects the safety and effectiveness of drugs. Laser particle counters are used to monitor the cleanliness of clean rooms to ensure compliance with GMP (Good Manufacturing Practice) requirements.
electronics industry
In the manufacturing process of semiconductors and electronic components, tiny particles may cause product defects. The use of laser particle counters can monitor the production environment in real-time and reduce product defect rates.
food industry
A clean environment for food production and packaging is also an important factor in ensuring food safety. By monitoring particulate matter, ensure that the production environment meets hygiene standards and reduce pollution risks.
medical industry
Maintaining a certain level of air cleanliness in hospital operating rooms and sterile rooms is an important measure to prevent infections. Laser particle counters can help monitor and maintain the cleanliness of these environments.
aerospace
Ensuring clean room air quality is key to ensuring product performance in the manufacturing of aerospace components. Laser particle counters can be used to monitor particulate matter in the air, ensuring that the manufacturing environment meets strict standards.
