Which Particle Counter Device to Use For Taking the Sampling Record at Data Center?
When selecting a particle counter device for taking sampling records in a data center to comply with ISO 14644-1 standards, it is crucial to use a device that meets specific performance requirements. Below are the key considerations and recommended particle counters for data centers.
Key Features to Look For in a Particle Counter for Data Centers
Compliance with ISO 21501-4:
- The device should comply with ISO 21501-4 to ensure accuracy, repeatability, and calibration.
- ISO 21501-4 is the standard for particle counter calibration and performance, ensuring reliable data.
Detection Range:
- Particle sizes must be measurable for 0.3 µm (microns) and larger, as these are critical thresholds for ISO 14644-1 compliance in data centers.
- Particle sizes of 0.5 µm and 1.0 µm are commonly monitored in cleanroom and IT environments.
Portability:
Use a handheld or portable particle counter for flexibility when moving between sampling locations in a data center.
Airflow Rate:
A minimum 1 CFM (Cubic Foot per Minute) flow rate is recommended for efficient air sampling. Higher flow rates can reduce sampling time.
Data Logging and Reporting:
Ensure the device can store data and generate reports for audits and compliance purposes.
Multiple Particle Channels:
A good particle counter should measure multiple particle sizes (e.g., 0.3 µm, 0.5 µm, 1.0 µm, 5.0 µm) simultaneously.
