Additional Specialty Services

Ultra-High Accuracy Length, Thickness and I.D./O.D. Measurement

  • 1 micro-inch resolution
  • Temperature compensation
  • Variable pressure or non-contact
  • Gage calibration

In line with our philosophy of thoroughness and exactitude, we can measure outside and inside diameters and lengths with extreme accuracy, repeatability, and speed, using a variety of contact and non-contact instruments with resolutions down to one-millionth of an inch!

Variety of Nondestructive Wall Thickness Measuring Capabilities

  • Complex castings
  • Forging webs and die closure
  • Plastic and glass bottles
  • Formed or drawn sheet metal
  • Pipes and tubes

Wall thicknesses of all types of materials can be nondestructively measured with an accuracy down to 0.0001 inches and a thickness of up to approximately 20 inches using ultrasonic distance measurement (high-frequency sound waves) and Hall-effect (perturbations in a magnetic field) technologies. The applications are innumerable, the process is fast, and the cost savings are great because sectioning for access to the measurement of interest is not required.


We can assist you in validating your own measurement processes either by performing the same measurements in our laboratory or by comparison of alternate methods and instruments. Further, Q-PLUS Labs can assist in the systematic assessment of the factors causing measurement variation.

Measurement Studies

Measurement studies are performed where uncertainty exists in determining the ideal combination of applied metrology technology and resources, particularly for long-term arrangements. This is essentially where we take the seemingly impossible measurement job and make it possible—then we prove it and, if desired, implement it into your production measurement process.

Potting and Sectioning Capabilities

Potting and sectioning is useful for accurate measurement when no type of contact or non-contact sensor will properly detect geometry for parts such as rubber bearing seals.

Blue, Scribe and Layout

Some of our customers require that castings and forgings be inspected using the traditional blue and scribe method so one can “see” how (and perhaps why) a casting conforms or does not conform to engineering requirements. We have the equipment and expertise to fulfill this increasingly rare (but still important) need as well.

Part Sorting and Separation

When a large lot of parts have been determined to contain defects or a manufacturing process could not be adequately controlled, the only viable option is to sort through the lot and separate the good from the bad. Q-PLUS Labs offers both automated and manual sorting and separation services. These services are geared toward comparably smaller lot sizes (hundreds or thousands), typically of more sophisticated parts and assemblies (including screw machined parts, sheet metal fabrications, die castings, plastic injection moldings, and numerous special processes). Customized sort criteria include visual defects, missing hardware or components, welds, commingling, marking & identification, omitted or unspecified geometrical features and, of course, highly detailed and accurate inspections for dimensional anomalies. Results can be qualitative (go/no-go) or quantitative accompanied by a variety of useful statistics.

Failure Analysis

Failure Analysis is performed (usually in conjunction with dedicated engineering and failure analysis firms) to provide advanced dimensional measurement capabilities as well as expertise in support of metallurgical, chemical, physical, functional, or other testing used to determine the cause of failure and preclude its recurrence.

Force Testing

Q-PLUS Labs provides a variety of force testing services to all industries for countless applications. Tests can conform to ASTM, BS, DIN, ISO and other methods.

  • Packaging quality
  • Seals
  • Textiles
  • Tissue

3rd Party Independent Laboratory Dispute Resolution

Occasionally, disputes arise between sub-tier manufacturers and their customers, between prime contractors and their suppliers, or between exporters and importers. Right or wrong, good or bad, sufficient or deficient, conforming or discrepant, we’ll get to the truth of the matter. A biased inspector is not an inspector at all, but rather a “rejector” or an “acceptor.” Our inspections are performed by real inspectors: dedicated professionals who are in the information business and who work to the highest ethical standards. Anything less would simply invalidate what we do. This means our measurement data is impartial, unbiased, rational, factual, and based on valid and repeatable observations.


High Definition Raster Scan Now Available from Q-PLUS Labs
We are now offering HD Raster Scanning that enables ultra-fast measuring speeds with increased accuracy. This is an exciting new capability which proves that even after 20 years of imaging processing in coordinate metrology, revolutionary developments are still possible today. To do so, images of the part are recorded at the maximum camera frequency while in motion and are then superimposed by a patented method to form an overall high-resolution image ...
