Clean Sensing System Advanced Clean-Monitoring for the Manufacturing Field

Is that booth really clean? Is clean air with a filter enough to maintain a clean environment? Clean measures are not perfect unless they are tied to quality. Localized Continuous Clean-Monitoring Systems by OMRON provide many ways to improve quality and enable perfect reporting of production process monitoring. Applications Electronic Component Production Processes Multi-Clean Control 2 Cell Production Processes Storage and Test Environments Direct Clean Control Storage of Precision and Optical Components

Unique and Easy Ionizer for Air Clean Unit Industry First Patent pending Ionizer That Can be Combined with Air Clean Units Previous Model When Using an Air Clean Unit Ionizer Laminar airflow can be disrupted with bar-type Ionizers, depending on where the Ionizer is installed, and too much installation work is required. Opening Constructed Not to Obstruct Laminar Airflow The opening does not obstruct the airflow from the Air Clean Unit eliminating worries about disrupting the laminar airflow. 6 The Ionizer can be mounted directly to the Air Clean Unit.

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...
