ng a contamination-free environment is a prerequisite for high-tech manufacturing and scientific research. Cleanrooms are central to this endeavour. Although a cleanroom is a critical part of maintaining a working environment, they cannot guarantee required cleanliness standards without robust monitoring systems such as particle counters and air quality monitors. A cleanroom particle counter directly contributes to air quality by measuring the concentration of airborne particles in the environment, which is essential for quality assurance (QA) and compliance. Here is a guide on how to choose the right particle counter for your cleanroom
Understanding Particle Counter Calibration and Flow Rates
Particle counters are calibrated at specific flow rates, measured in cubic feet-per-minute (CFM) or litres-per-minute (LPM). The sizing accuracy of a particle counter is dependent upon that flow rate. To meet the most stringent contamination specifications, cleanroom particle counters must sample defined volumes of air; this provides confidence in the particle data and is often stated as statistical significance.
Meeting ISO Standards with Your Particle Counter
When the primary application is cleanroom certification, an instrument with ISO certification features simplifies the process. The particle testing method must be accurate, reliable, and repeatable. Modern cleanrooms typically require ISO Class 5 or Class 6, referring to a level of air cleanliness, and most modern cleanroom particle counters can meet said levels of air cleanliness with ease.
Leveraging Digital Connectivity for Efficient Monitoring
In today’s interconnected digital age, the ability to connect your particle counter to a computer or network for remote monitoring and data collection is a significant advantage. This feature allows for real-time data analysis, immediate response to any changes in the cleanroom environment, and seamless integration with other systems. It provides convenience and flexibility in monitoring particle levels and managing cleanroom operations.
The Impact of Flow Rate on Particle Counter Selection
Flow rate is another crucial factor to consider when choosing a particle counter. Different counters have varying flow rates, which can significantly impact the speed of measurements. Therefore, it’s essential to select a particle counter with a flow rate that aligns with your specific application.

sing the Right Particle Counter for Your Particle Size
The size range of the particles you aim to monitor will also influence your choice of particle counter. Some counters are better equipped to handle larger particles, while others excel at detecting smaller particles. Understanding your monitoring needs will help you select the right cleanroom particle counter.
Determining the Number of Particle Counters for Your Cleanroom
The size and complexity of your cleanroom will determine the number of particle counters you need. A larger cleanroom or one with multiple zones may require multiple counters to ensure accurate monitoring across the entire space.
The Importance of Sample Point Locations in Cleanrooms
Lastly, the location of your particle counter is of utmost importance. Factors such as airflow patterns, potential sources of contamination, and accessibility should guide your decision when choosing sample point locations.
