From medical devices to automotive parts, accuracy is critical to the success of your manufacturing business — and perhaps, to the life of your customer. And now we have even more expertise to help you.


Determining the capability of a process is one of many important duties involved in the world of metrology, which improves overall quality assurance and dependability in manufacturing.

In manufacturing, the term “metrology” is generally used when referring to quality inspection, such as manual layout inspection, as well as coordinate measuring machine inspection. More specifically, metrology in manufacturing is the study of how to reliably measure and manufacture a product.

Industrial Inspection and Analysis’ (IIA’s) accredited metrology labs across the U.S. utilize the latest technology and the most experienced people to provide value-added metrology solutions to highly regulated industries, including aerospace, medical device, defense and more.

We strive to provide Story Worthy Service – we’re here to serve you. IIA provides dimensional metrology, advanced GD&T inspection, advanced 3D scanning, modeling, analysis, and geometry re-creation to customers in every industry and in every phase of product design and production. We can provide quick turn inspection services for large and small quantities of parts. We utilize a vast array of tools for different challenges: blue and red-light laser scanners, CT scanners, Touch Probe CMMs, Optical CMMs, Profilometers, and all the other inspection equipment you would find in a well-equipped laboratory.

Choosing the right instrument:

From a few points of data to thousands of points, our technicians utilize the right equipment for each project to be as effective and efficient as possible. Each type of equipment has strengths and weaknesses, depending on the application. We consider the tolerances of the blueprint, the type of material, and the geometry of the product to match the right tool with each project.

  • Touch Probe Coordinate Measuring Machines (CMM) are the most widely used instrument to capture tactile data of a physical component. These can be used to extract singular points or many points when used in scanning mode. The data provides feedback on distances and features and allows for comparison between them. This type of equipment is extremely accurate and versatile.
  • Vision CMMs utilize highly accurate cameras in conjunction with the accurate movement of the instrument to gather image data of distances and features. These also can gather singular points of data or many points. When materials are very soft, fragile, or easily scratched, a vision system may be the perfect tool to get the job done.
  • 3D Laser scanning equipment enables our team to capture a very large amount of data very quickly. Products can range in size from a penny to an airplane or larger. There is a tradeoff between the amount of data and the accuracy of the data, but for getting feedback on manufacturing processes, this is one of the best ways to go.
  • Industrial CT Scanning equipment is a highly accurate way of capturing large amounts of data, however it doesn’t have the speed of laser scanning equipment. There is also nothing better suited to get data about internal features and geometry. With some limitations in material type and size, this application isn’t for every product, but does a fantastic job when it’s the right fit.
