Particle counter calibration is critical for industries like pharmaceuticals, semiconductors, and aerospace, where even a single airborne particle can cause batch failure or regulatory non-compliance. With over 30 years of expertise, Techmaster Electronics delivers calibration services that ensure cleanroom integrity and ISO audit readiness.
What Is a Particle Counter and Why Calibration Matters
A particle counter measures airborne or fluid-based particulate matter. These devices are commonly used in cleanrooms to ensure contamination levels remain within regulated limits.
Industries that Rely on Particle Counter Calibration
-
Pharmaceuticals & Biotech – Ensuring sterility in GMP-compliant manufacturing
-
Semiconductors & Electronics – Preventing microscopic defects in sensitive components
-
Aerospace & Medical Devices – Meeting safety-critical precision standards
-
Food Processing – Maintaining hygiene for consumer safety
Without routine particle counter calibration, devices can drift, leading to non-compliance with ISO 21501-4, GMP, or FDA requirements.
Why Particle Counter Calibration Is Essential for Compliance
Regular calibration prevents:
-
Inaccurate measurements that lead to failed audits
-
Regulatory breaches and the risk of losing ISO/GMP certifications
-
Operational downtime, batch rejections, or product recalls
-
Loss of customer trust due to quality lapses
Techmaster’s ISO/IEC 17025-accredited calibration services ensure particle counter accuracy verification aligned with industry standards.

In-House vs. Professional Particle Counter Calibration
| Criteria | In-House Calibration | Techmaster Calibration |
|---|---|---|
| Accuracy & Traceability | Basic tools, limited experience | NIST-traceable, ISO/IEC 17025 |
| Compliance | Risky for GMP/ISO audits | Meets ISO 21501-4 and FDA |
| Documentation | May lack full data | Certificates with uncertainties |
| Resources Needed | Equipment, SOPs, trained staff | Turnkey, zero burden |
| Downtime Risk | Higher due to delays or errors | On-site service available |
How Often Should Particle Counters Be Calibrated?
-
Annually, based on most manufacturers’ recommendations
-
Every 6 months, for dusty or high-risk cleanrooms
-
Before audits, especially for GMP-regulated operations

Frequently Asked Questions (FAQ)
Q1: What’s the difference between calibration and verification?
A: Calibration adjusts device output and includes a traceable certificate; verification only confirms current accuracy.
Q2: Can I calibrate my particle counter on-site?
A: Yes, Techmaster provides ISO/IEC 17025-accredited on-site calibration services.
Q3: What’s included in the certificate?
A: Measurement results, uncertainty values, NIST traceability, and ISO 21501-4 conformity.
Q4: What are particle counter maintenance services?
A: Regular inspections, cleaning, and minor adjustments to prevent drift and ensure longevity.
