Procedures for measurement in high concentration environments (such as oil mist environments).

Procedures for measurement in high concentration environments (such as oil mist environments).

The important point is to keep the flow going and discharge it outside!

Our counter has a counting error (count loss) of 15,000,000 CFM (cubic feet per minute = 28.3L) within 10%. This allows for high concentration measurements, meaning it can distinguish between high and low count values. However, counting means that high concentrations of foreign substances and mist will enter the flow path (optical sensor, tube, pump). Therefore, we will guide you on how to measure without damaging the particle counter. 【Measurement Method】 ■ Set up sampling 1. Set sample time to 6 seconds 2. Set hold time to 5 seconds 3. Set cycles to 10 4. Before measurement, attach the purge filter and confirm zero count 5. After starting the measurement, once the third count of the target measurement cycles is completed, attach the purge filter to the inlet 6. If the final screen at the end of the measurement does not approach zero count, restart the measurement as is until the count value approaches zero *For more details, please refer to the PDF document or feel free to contact us.

[Data] Particle Counter and Large Particles

[Data] Particle Counter and Large Particles

The ISO cleanliness level is clear! But why is the work surface contaminated? We will answer that.

This document introduces particle counters and large particles. It addresses the question, "Are there no large particles in clean rooms?" as well as issues such as "Is it just that they are not being measured?" and includes references on gravitational settling, the particle size of contaminants that should be managed (e.g., thin films, laminating, painting processes), among others. It responds to the misconception that particle counters can handle everything from small to large particle sizes. [Contents] ■ Are there no large particles in clean rooms? ■ Is it just that they are not being measured? ■ Reference 1: What about the gravitational settling of particles? ■ Reference 2: What particle sizes of contaminants should be managed? (e.g., thin films, laminating, painting processes) ■ Reference 3: Real-time mode = seeing what is happening right in front of you *For more details, please refer to the PDF document or feel free to contact us.

[Data] Article: A mere particle counter, yet a particle counter.

[Data] Article: A mere particle counter, yet a particle counter.

Particle counters are not exclusively for clean rooms. They are expanding their applications from traditional production sites to everyday environments.

In recent years, OPC (Optical Particle Counter) is expanding its use beyond clean rooms (CR), that is, into new settings such as work environments, indoor environments, and atmospheric environments. This document considers new applications of OPC that are not limited to tools for monitoring CR cleanliness. We have reprinted an article published in the Clean Technology magazine. Please take a moment to read it. [Contents] ■ Introduction ■ Overview of OPC as a cleanliness monitoring device for CR ■ New settings, environments, and applications for OPC ■ Suggestions for new applications ■ Conclusion *For more details, please refer to the PDF document or feel free to contact us.

Particle Counter "Model 5301C・5501C"

Particle Counter "Model 5301C・5501C"

Achieving inline measurement! A pressure air-compatible particle counter using a self-compensating free jet sensor.

Until now, particle counters were thought to only be capable of suction sampling under atmospheric pressure due to the structure of the sensors, and were unable to measure particles in compressed air or gas. On the other hand, with the institutionalization of HACCP and the transition to ISO 22000 (June 2021), it has become necessary to manage dust, bacteria, water, and oil for gases that come into direct or indirect contact with food. Additionally, there is a significant demand for cleanliness monitoring in pneumatic systems such as ProAir. The Particle Plus 'Model 5301C・5501C' has achieved direct measurement of particles in pressurized air through its unique self-compensating free jet sensor. 【Features】 ■ Self-compensating free jet sensor adopted ■ Six selectable particle size settings ■ Data collection in 1-second intervals (45,000 logs) ■ Real-time meter ■ Multi-point monitoring software AMOSYS *For more details, please refer to the PDF document or feel free to contact us.

Particle Counter "5300/5500・5300/5500P"

Particle Counter "5300/5500・5300/5500P"

From the clean room, it supports high particle concentrations for indoor environments, atmosphere, high-concentration exposure experiments in chambers, and working environments!

The "5300/5500・5300P/5500P" is a particle counter that can be installed on walls or columns, used on a tabletop, operated directly from the unit, or remotely controlled from a computer.
