Small Size, Continuous Measurement In-line Air Particle Sensor Smallest in the Industry Air Particle Sensor for In-line Measurement A high-performance fan for external air suction enables constant measuring over long periods. Semiconductor lasers and high-sensitivity optical design in the sensing section enable measurement of 0.3-µm particles. Airflow Laser beam Measurement Principle A semiconductor laser beam is targeted on to the air intake and the light is scattered when particles pass through that beam. The scattered light is received by the light receiving element and converted to an electrical...

Clean Sensing System On-screen Indication and Data Logging of Particle Amount Measurement values can be easily logged on a personal computer by using the Interface Unit and special software (sold separately). Data from sequential sensing of particles can be used to improve quality. Quality Control with Multi-point Measurement Realtime Clean Air Monitor A variety of displays (including color graphs for visual confirmation by color of particle densities, indication of the number of particles, and trend graphs) can be set. Particle Sensors and Interface Units can also be set from the personal computer....
