Composition Description of Clean Room Environment Online Monitoring System
The system is mainly used for real-time monitoring of environmental parameters in clean rooms, and completes functions such as data storage and management. The system combines laser sensing technology, computer network technology, and information processing technology. It consists of monitoring equipment such as particle counters, temperature and humidity sensors, differential pressure sensors, wind speed sensors, signal transmission and reception modules, main control computers, monitoring software, etc. Real time monitoring of clean room cleanliness, temperature and humidity parameters can be achieved, and other modules can be added according to user needs.
Installing an online dust particle counter in the clean room area can avoid human interference. The main control computer remotely monitors the particle status of each sampling point, and the monitoring results are directly transmitted to the main control computer, achieving online multi-point monitoring and remote centralized control management, greatly improving the monitoring quality and level of the clean space. It is an environmental monitoring equipment necessary for the comprehensive implementation of GMP standards in drug production, and an essential instrument for improving production environment monitoring quality and product yield in clean scenes such as electronics factories, hospital operating rooms, aerospace, precision processing, and food industries. The counting efficiency and accuracy of the counter comply with the technical requirements of JJF1190-2008 "Dust Particle Counter Calibration Specification" issued by the State Administration of Metrology.
OSEN-Z5108 Online Laser Dust Particle Counter (28.3L)
The OSEN-Z5108 high flow built-in pump 28.3L online laser dust particle counter is a testing instrument used in the fields of cleanliness monitoring, particle counting and detection in clean environments. The counter is based on the principle of light scattering and uses photoelectric sensing technology to detect the particle size and count the number of dust particles. Compared to small flow counters, this instrument has a sampling flow rate of 1CFM (28.3L/min), with a larger sampling flow rate and more accurate detection, suitable for clean environments of Class 100 and Class 10; Suitable for clean environments such as electronics, semiconductors, LCD panels, pharmaceuticals, aerospace, precision machining, hospitals, research institutes, etc.
