What is a Falling Dust Counter? A falling dust counter is a device that measures the amount of dust and foreign substances (falling dust) that adhere to the surface of products. By measuring not only the tiny particles suspended in the air but also the larger particles (10μm to 100μm) that adhere to products and cause defects, it is possible to identify foreign substances that lead to defects and implement countermeasures. Features of the Falling Dust Counter ■ Measurement of Large Particles: Measures large particles (falling dust) that are 10μm or larger, which cannot be measured by conventional particle counters. ■ Classification Function: Classifies falling dust by size and displays the count. Helps understand the size of dust and foreign substances, contributing to identifying the cause. ■ Rapid Measurement: Measurement time is quick, approximately within 40 to 50 seconds. ■ Compliance with ISO14644-17: Complies with ISO14644-17 established in February 2021. It can serve as a direct management indicator for large particles that cause defects. For quality improvement and yield enhancement, please consider introducing a falling dust counter.

Are you accurately identifying the true nature of debris and foreign substances larger than 100μm that cannot be captured by falling dust counters or particle counters? The root cause of quality defects in manufacturing environments often lies in the overlooked coarse particles. The "Duskare 100 BLACK" is an innovative debris and foreign substance investigation device specifically designed to address this issue. This product uses a micro-adhesive dust sampler to reliably collect coarse particles such as fiber debris, metal scraps, and resin pieces that are difficult to sample. Its greatest feature is the automatic classification and counting system for the collected debris and foreign substances. This eliminates the variability caused by visual confirmation in traditional methods, significantly reducing measurement time. Regardless of who conducts the measurement, it is possible to obtain objective and highly accurate data. The measurement results are displayed in color-coded categories based on the type of foreign substance, providing hints for identifying contamination sources and contributing to efficient countermeasure planning. With a proven track record in a wide range of industrial fields, from general work environments to clean rooms, it is an essential tool for maintaining and improving cleanliness and clean environments.
