NIST is unique as the national measurement science institute. We are the U.S. agency responsible for maintaining measurement standards, from the second to the kilogram.
We help ensure that these units of measure are consistent across our watches and our grocery scales. But this…
The need for long-range height measurements has been around since the principles of layout work became a fundamental requirement in machine shops.
The first step in the manufacturing process is to lay out a piece by transferring a design or pattern to a workpiece. This is…
Our solar system has fascinated mankind for thousands of years. Astronomical research is looking for answers to the big questions of human existence. How big is the universe? How did it come into being? Astronomers all over the world use telescopes to cast their gaze into space.

Compliance with industry regulations and standards is a fundamental part of medtech. Without proper medical device compliance, companies risk patient harm, litigation, and reputational damage.
Fortunately, compliance with medical device regulations and standards is not an…
W ith the rapid digital transformation of manufacturing, including technologies like cloud solutions, digital twins, next-generation devices, automation, and AI, the role of metrology is poised for a transformative evolution. What can we expect from new quality systems, and how is the metrology…
The jet in pneumatic dimensional (or air) gauging is the mechanical part of the sensing probe—air plug gauge, air ring gauge, air caliper gauge—through which compressed air is directed onto the part under measurement.
In its simplest form, we have two jets working in tandem facing…
