PQI Calibration Services

PQI offers ISO/IEC 17025:2017 accredited CMM calibration service to both the ASME B89.4.1 and the ISO 10360 specification. We have factory trained technicians with 20+ years of experience and have an inventory of both Renishaw and Hexagon probe heads, touch probes and styli. We use the state-of-the-art Koba bar length standards for bi-directional testing and we perform dynamic ball bar tests for volumetric accuracy. Repair services and Renishaw RBE services are available.

Our Standard of Excellence

Our service engineers calibrate, repair and certify all makes and models of CMMs while specializing in Brown & Sharpe, DEA, Hexagon and Sheffield CMMs with full factory trained and authorized engineers with full access to software error correction. Certifications comply with national standards and all of our calibration equipment is traceable to NIST.

It’s not what’s on the front of the sticker, it’s what's behind it.

This sticker costs 32 cents to make, but the data behind it is priceless. Our people, procedures, equipment and facilities are second to none. And that is why we would like to be your choice for all your calibration needs:

  • Calibration data ensures the validity of measurement results.
  • Failed measurement results have consequences large and small.
  • Hubble Telescope mirror distortion: A $950 million dollar measurement error.
  • Failed measurement of heart pacemaker seals: 7 Deaths, $30 million dollar settlement: Don’t trust the sticker: Trust what’s behind it, let us show you the PQI difference.

Offered PQI Calibration Services

Dimensional Gaging

We offer gage calibration services and technical support for all your dimensional measurement activities, including hard gages and precision hand tools. We have a fully equipped, environmentally controlled lab onsite where we can conduct accredited calibrations with uncertainties as low as .000002".


All electronic test instruments require calibration to provide accurate test data. PQI offers electronic calibration for a wide range of commercial off-the-shelf equipment. We are a leading resource for NIST traceable ISO/IEC 17025:2017 accredited calibrations.

Physical Calibration

Our physical calibration services include torque, force and pressure calibration. We can calibrate pressure gages from vacuum to 10,000PSI. We offer service at your facility when appropriate and can calibrate most items in our lab.

CMM & Vision Systems

Our ANAB accredited services include calibration, repair and certification of all makes and models of CMMs. We have factory trained calibration technicians that provide linear and volumetric error correction on Hexagon, Brown & Sharpe, DEA and Sheffield CMMs. All of our certifications comply with national standards, and all of our calibration equipment is traceable to NIST.

CNC Machine Tool

Our CNC calibration specialists have the latest tools for analyzing CNC machine tools, including: laser interferometers, telescoping ball bars, spindle analysis systems and rotary table calibrators. Calibration capabilities include accredited ASME B5 Standard and Boeing CNC verification services.
