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.
