Key takeaways

  • Particle counters used in data centers must comply with ISO 21501-4 to ensure accuracy, repeatability, and reliable calibration data.
  • Devices must be able to measure particle sizes of 0.3 µm and larger to meet critical ISO 14644 compliance thresholds in data centers.
  • Handheld or portable particle counters provide necessary flexibility when moving between sampling locations within a data center.
  • Selected particle counters should feature data logging, reporting capabilities, and the ability to measure multiple particle sizes simultaneously.

Which Particle Counter Device 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 14644compliance 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.

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.
