The development of precision probes dates back to the 1920s with different mechanical touch devices, but significant advancements came with the advent of Coordinate Measuring Machines (CMM) in the late 1950s. This led to the creation of contact and non-contact probes, including mechanical triggers and scanning probes, as well as laser and ...
Lux meter for measuring illuminance, i.e. incident luminous flux per unit area; Luminance meter for measuring luminance, i.e. luminous flux per unit area and unit solid angle; Light meter, an instrument used to set photographic exposures. It can be either a lux meter (incident-light meter) or a luminance meter (reflected-light meter), and is ...
Mitutoyo America Corporation was formed in 1963 and is headquartered in Aurora, Illinois (just outside Chicago).Mitutoyo America offers the full product line of precision measuring tools, instruments and equipment with a distribution network, training and education classes, software development, and service support to provide a comprehensive metrology organization.
Modern measurement equipment includes hand tools, CMMs (coordinate-measuring machines), machine vision systems, laser trackers, and optical comparators. A CMM is based on CNC technology to automate measurement of Cartesian coordinates using a touch probe, contact scanning probe, or non-contact sensor. Optical comparators are used when ...
With a laser measuring tool, the job can be completed by one operator with just a line of sight. Although tape measures are technically perfectly accurate, laser measuring tools are much more precise. Laser measuring tools typically include the ability to produce some simple calculations, such as the area or volume of a room.
a device used for measuring holes. Hole gauge [3] used to gage internal dimensions of bores that are either too small in diameter for an inside micrometer, and have greater economy than a bore gage or other precision internal gage. Caliper: a device used to measure the distance between two opposing sides of an object. Center gauges and fishtail ...

They allow, for example, the measuring of a narrow o-ring groove. Pitch-diameter micrometers (aka thread mics) have a matching set of thread-shaped tips for measuring the pitch diameter of screw threads. Limit mics have two anvils and two spindles, and are used like a snap gauge. The part being checked must pass through the first gap and must ...
