We will be exhibiting our particle visualization system at the 38th Monozukuri World [Tokyo] 'Measurement, Inspection, and Sensor Exhibition' (July 1-3, 2026 / Tokyo Big Sight, South Hall 1, S1-33).

This is a portable particle detection device that can simultaneously visualize and count fine particles for quantitative management of fine particles.

The mobile particle visualization and counting system "Type-S" allows for the visualization and counting of suspended particles simultaneously and in real-time, without the need for knowledge of visualization or photography techniques, and with extremely simple operation. The visualization video of the particles and the counting values are continuously displayed on the attached monitor via dedicated software. Additionally, these results can be saved to a file, enabling highly traceable and persuasive particle management. Equipped with a mobile battery, it can be freely transported within the factory without power cords while exploring the source of generation. It can also be mounted on a tripod for fixed-point observation. It can serve as a tool for improving operational efficiency in response to the demand that "traditional measurement methods for particles lack space, manpower, and time." It is recommended for the following concerns: ■ I want to find the source of dust... ■ I want to locate leaks in high-performance filters... ■ I want to visualize and count in real-time... ● We provide product introductions and demonstrations via the web. Please take advantage of this. ● For more details, please download the catalog or contact us through our website.

The causes of defects are 'visible.' Identify the source and flow of foreign substances and lead to improvements on the spot.

"Unexplained foreign substances do not disappear" and "Even with countermeasures, they recur" — we solve such on-site issues all at once with our fine particle visualization system. This service uses laser light and a high-sensitivity camera to "visualize" invisible fine particles and airflow movements in real-time, providing a field investigation solution to identify the root cause of defects. We visualize "where it occurs, how it moves, and where it adheres" on-site, which could not be grasped with conventional measurements. Factors that are intricately intertwined, such as work actions, equipment structure, and transport processes, can be intuitively understood through video. This enables a reliable investigation of causes that does not rely on intuition or guesswork. Furthermore, based on our extensive field experience, we also provide specific improvement proposals based on the visualization results. We support comparative evaluations before and after improvements, which is a significant feature as it allows the "effects of countermeasures to be visible." Our system has been widely adopted in fields such as semiconductors, films, pharmaceuticals, and food, where strict quality control is required, contributing to the reduction of defects and prevention of recurrence in a short period. ■ Numerous example videos are available on our company website.
