Product Introduction
Laser Dust Particle Counter - Product Overview
The laser dust particle counter is a dust particle detection device based on the laser scattering principle. Search keywords: laser dust particle counter, cleanroom online monitoring, dust particle counter. This instrument can continuously detect the number of dust particles of different sizes in a cleanroom, and is suitable for clean environment monitoring in industries such as pharmaceuticals, electronics, hospitals, and food. In cleanroom online monitoring, the laser dust particle counter can reflect changes in cleanliness in real time, helping enterprises promptly identify pollution sources and take control measures.
Laser Dust Particle Counter - Working Principle
The laser dust particle counter uses a laser light source to illuminate the sampled airflow. When dust particles pass through the laser beam, they generate scattered light, which is received by a photodetector and converted into an electrical signal. The particle size and concentration are then calculated based on the signal amplitude and quantity. In cleanroom online monitoring, the laser dust particle counter can simultaneously measure multiple particle size channels such as 0.3μm, 0.5μm, 1.0μm, 3.0μm, 5.0μm, and 10μm. The instrument has fast response speed, stable sampling flow rate, supports RS485, Modbus, and 4-20mA output, and can be connected to a cleanroom monitoring system.
Laser Dust Particle Counter - Application Scenarios
Laser dust particle counters are widely used in clean areas of pharmaceutical factories, electronics factories, hospital operating rooms, food workshops, and laboratories. In cleanroom online monitoring, laser dust particle counters can be installed in key process areas, personnel entrances and exits, and return air ducts. The instrument can be linked with air conditioning and purification systems, audible and visual alarms, and monitoring platforms to achieve automatic adjustment and alarms. For cleanrooms that require continuous monitoring, laser dust particle counters can also form a multi-point monitoring network and upload data uniformly to a control center.
Laser Dust Particle Counter - Technical Advantages
The laser dust particle counter has advantages such as high detection accuracy, fast response speed, and good stability. In cleanroom online monitoring, the laser dust particle counter uses a long-life laser light source and an anti-contamination optical design, making it suitable for long-term operation. The instrument supports data storage, printing, and remote communication, and is easy to maintain. When choosing a laser dust particle counter, attention should be paid to particle size channels, sampling flow rate, detection range, accuracy, and communication method to ensure it meets cleanroom online monitoring needs.
