パーティクルプラス Company Overview

We provide cutting-edge sensor technology and extensive knowledge. Clean control is a keyword for the future for both companies and consumers.

"Just a particle counter, but still a particle counter" Particle Plus Co., Ltd. designs and manufactures particle counters and air quality monitoring instruments equipped with advanced sensors and a wealth of features. We provide technology, expertise, and services to production environments and living spaces that require clean environments, such as life sciences, food and beverage, pharmaceuticals, indoor air quality, atmospheric environment, industrial hygiene, cosmetics, semiconductors, aerospace, and data storage industries. Our company helps you stay ahead of the times by offering unique particle sensors, counters, and insights based on cutting-edge technology.

Business Activities

■Design and manufacturing of particle counters ■Design and manufacturing of air quality monitoring instrumentation ■Consultation on cleanliness control and management

Recommended information

30μm large particle counter

30μm large particle counter

Large particles are troublesome, and I want to detect them! However, they are difficult to find! This is where particle counters and know-how come in handy.

The Particle Plus large particle-compatible particle counter detects particles ranging from 0.5 µm to over 30.0 µm. The particle counter measures airborne particles "easily," "in real-time," "by anyone," and "on-site." However, only particles with small diameters can be considered airborne, as they are affected by Brownian motion from air molecules and experience air resistance, allowing them to remain suspended for long periods. In contrast, larger particles do not continue to float and settle (fall) quickly, and they have a low occurrence frequency that does not align with the particle size distribution pattern of atmospheric dust. It is understandable that there are concerns about the phenomenon of contamination by large particles in clean rooms, as well as the issue of having small particles being acceptable while large particles are not. For a particle counter, particles that are difficult to suspend and those that fall outside the premise of isokinetic sampling are very challenging to measure. As particles increase in size, the factors contributing to gravitational settling significantly increase compared to suspension. The particle counter cannot draw in falling particles by bending their trajectory. Opening the sampling inlet and waiting for falling particles to enter is purely a matter of chance. It is essential to measure this accurately. We are always available to assist, not just for demonstrations of the measuring instrument.

40th Aerosol Society Conference 2025 (Himeji - August 27 to 29) Update

  • PRODUCT

This is the material used at the luncheon meeting of the Japanese Aerosol Society (JAAST) held at the Himeji Chamber of Commerce from August 27 to 29 (although it was not displayed on the screen due to system issues). While light scattering particle counters have aspects that are not well-suited for aerosol measurement, they have become essential in the field of contamination control, where in-situ capability, compact size, and ease of use are required. However, they are primarily used in clean rooms, and measuring larger particles in a wider range of environments was previously considered unconventional. We have been using particle plus fine particle counters that can handle high particle concentrations and larger particles in various harsh environments, accumulating various insights. This is a simplified document summarizing some of those insights.
