Additional Inspection Specialties

Non Contact MeasurementUltra High-Accuracy Length, Thickness and I.D./O.D. Measurement

  • 0.000001 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 on an inch!

Variety of Nondestructive Wall Thickness Measuring Capabilities

  • Complex Castings
  • Forging Webs & Die Closure
  • Plastic and Glass Bottles
  • Formed or Drawn Sheet Metal
  • Pipes & Tubes

Wall thicknesses of all types of materials can be nondestructively measured with an accuracy down to 0.0001 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 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 comparison of alternate methods and instruments. Further, Q-PLUS 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 & Sectioning Capabilities

When no type of sensor, contact or non-contact, will properly detect geometry for parts such as rubber bearing seals, accurate measurement may not be feasible without potting and sectioning.

Blue, Scribe & 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 doesn't conform to engineering requirements. We have the equipment and expertise to fulfill this increasingly rare but important need, as well.

Part Sorting & 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 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.

3rd Party Independent Laboratory Dispute Resolution

Occasionally, disputes arise between sub-tier manufacturers and their customers, prime contractors and their suppliers, or exporters versus 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 work to the highest ethical standards. Anything less would simply invalidate what we do. That means impartial, unbiased, rational, and factual measurement data based on valid and repeatable observations.
