With the adoption of a CCD camera, the boundaries of each layer are clear! You can change the colors and shades of the image!

The "Model 518PC" is a dry film thickness gauge equipped with a CCD camera in the microscope section. Using software, the boundaries of each layer in the cut image are specified with circles, and the film thickness is automatically calculated based on the distance of each layer and the angle of the drill. Additionally, if the boundaries of the layers are difficult to distinguish, this product allows for changes in the color and shading of the image, making the boundaries of each layer clearer. We also offer the "Model 518MC," which can measure multilayer coating film thickness by layer. 【Features of Model 518PC】 ■ Easily calculate the film thickness of each layer with software ■ The use of a CCD camera makes the boundaries of each layer clear ■ Capable of saving numerical data and images ■ Allows for retrieval and recalculation of image data ■ Reduces individual differences in measurements *For more details, please refer to the PDF document or feel free to contact us.

A spray droplet particle measurement system that replaces phase Doppler method and laser diffraction method.

AOM Systems' SpraySpy is a completely new spray droplet/spray particle measurement system that uses a unique pulse displacement method (Time-Shift technique). It has obtained international patents and can simultaneously measure the size, velocity, and particle density of opaque or non-spherical particles and high-density spray particles, which was difficult with existing technologies such as phase Doppler method or laser diffraction method. Additionally, since the laser emission and detection parts are the same for detecting backscattered light, it eliminates the need for complicated adjustments of the detection part's position.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
