Precision Pressure & Mechanical Measurement for Controlled Environments

In cleanrooms, containment zones, and manufacturing facilities, precise pressure control is vital for maintaining pressure cascades, verifying airflow differentials, and ensuring structural and mechanical safety. We provide rigorous, NIST-traceable calibration for an extensive range of pressure and mechanical instruments, ensuring your gauges and transducers perform within exact manufacturer and regulatory thresholds.

Core Pressure & Mechanical Calibration Capabilities

Specialized Calibration Ranges & Instrumentation
  • Absolute Pressure Gauges & Pneumatic Systems

    Precision calibration for absolute pressure gauges spanning 0 to 40 Bar (pneumatic), ensuring exact baseline reference performance under operating pressures.

  • Differential Pressure Gauges & Manometers

    Specialized calibration for cleanroom differential pressure gauges and manometers covering -1000 to 1000 mmWC, verifying low-pressure differential accuracy for critical room cascades and airlocks.

  • Pressure Transducers & Transmitters

    Output signal verification (current and voltage loops) for electronic pressure transmitters integrated into building management and HVAC systems.

  • Torque & Mechanical Tools

    Calibration and tension verification for torque wrenches and mechanical assembly tools used in cleanroom structural builds and equipment maintenance.

Our Pressure Calibration Process

A Rigorous Step-by-Step Metrology Protocol

  1. Phase 1

    Initial Inspection & As-Found Data

    Inspecting mechanical linkages, checking zero-points, and recording initial “As-Found” pressure responses across the designated range.

  2. Phase 2

    Standard Reference Comparison

    Benchmarking test gauges and transducers against high-accuracy digital pressure controllers and pneumatic dead-weight testers.

  3. Phase 3

    Adjustment & Linearity Tuning

    Adjusting span and linearity across full operational ranges (including 0–40 Bar pneumatic and -1000 to 1000 mmWC differential scales).

  4. Phase 4

    Certification & Audit-Ready Handover

    Issuing an ISO/IEC 17025 accredited calibration certificate containing complete As-Found/As-Left data, environmental conditions, and NIST traceability.

Frequently Ask Questions

  • What pressure ranges do you support for absolute and differential gauges?

    We calibrate absolute pressure gauges up to 0–40 Bar (pneumatic) and differential pressure gauges ranging from -1000 to 1000 mmWC.

  • Can you calibrate differential pressure gauges used in cleanroom airlocks?

    Yes. We specialize in low-pressure differential gauges and magnehelic meters used to monitor cleanroom pressure cascades and containment zones.

  • Do you test electronic outputs for pressure transducers?

    Yes. We specialize in low-pressure differential gauges and magnehelic meters used to monitor cleanroom pressure cascades and containment zones.

  • What documentation is provided with the calibration?

    Every instrument receives an audit-ready certificate detailing As-Found/As-Left data, measurement uncertainties, and full NIST traceability numbers.
