A micrometer can measure the thickness of a human hair. If you need this kind of accuracy, here are some of the best ...

As one does I found myself browsing, one thing led to another, and I bought a micrometer screw gauge. While micrometers are pretty expensive devices, reflecting their high precision engineering ...

Mechanical micrometers are instruments for precision dimensional gaging consisting of a ground spindle and anvil mounted in a C-shaped steel frame. They are available in Vernier scale, digital and ...

A couple of years ago we published a look at precision measurement tools, in particular vernier calipers and micrometer screw gauges. It featured a look at how they work and how they’re used ...

Laser micrometers measure extremely small distances using laser technology. Laser micrometers are used in both laboratory and production settings. In production setting, CCD or shadow based laser ...

Laser micrometers are capable of measuring outside diameter for mechanical engineering and machining purposes. Within the micrometer is a transmitting unit responsible for emitting a laser beam that ...

Cells can vary between 1 micrometer (μm) and hundreds of micrometers in diameter. Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called ...

A simple, fairly accurate, and easily-made apparatus of the micrometer form may be constructed as follows: Get a common iron or brass bolt about y of an inch in diameter and about 2% inches long ...

German thimbles, clay pipes and rat bones have been among the finds at a dig at a disused pub. Human remains were also discovered during the excavations of a path and part of the churchyard next ...

Microfluidics is an interdisciplinary field that combines principles from physics, chemistry, and engineering to create devices that can process and analyze minuscule volumes of liquids. Often, ...
