Our Pressure Calibration Process

A Rigorous Step-by-Step Metrology Protocol

  1. Phase 1

    Initial Evaluation & As-Found Data

    Performing baseline zero checks, inspecting optical and mechanical assemblies, and recording initial “As-Found” performance data on your manufactured PMS units.

  2. Phase 2

    Component Tuning & Flow Verification

    Cleaning internal optics, adjusting sampling pumps, and verifying volumetric flow rates using certified primary standards specific to PMS architecture.

  3. Phase 3

    Standard Challenge & Accuracy Testing

    Verifying particle size channels, concentration limits, and sampling volumes against certified reference standards according to Particle Measuring Systems specifications.

  4. Phase 4

    Certification & Audit-Ready Handover

    Issuing a comprehensive, ISO/IEC 17025 accredited calibration certificate detailing As-Found/As-Left data, environmental conditions, and NIST traceability.

Frequently Ask Questions

  • Are you an authorized service provider for Particle Measuring Systems (PMS)?

    Yes. Our technicians are factory-trained and authorized to perform level calibration and maintenance on equipment designed and built by Particle Measuring Systems.

  • What documentation is provided with the calibration certificate?

    You receive a fully compliant, audit-ready certificate containing complete As-Found and As-Left data, flow rate verifications, channel accuracy checks, and NIST-traceable standards documentation.

  • Do you offer on-site calibration for fixed cleanroom systems?

    Yes. For fixed cleanroom installations and hard-to-reach sampling points, we provide specialized on-site mobile calibration services to minimize facility downtime.

  • How often should PMS equipment be calibrated?

    Industry standards and Particle Measuring Systems manufacturer guidelines typically require annual (12-month) recalibration to maintain ISO compliance and reliable data integrity.
