Bore gauge: 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.
The French scale, French gauge or Charrière system is commonly used to measure the size of a catheter. It is most often abbreviated as Fr, but can often be seen abbreviated as Fg, FR or F. It may also be abbreviated as CH or Ch (for Charrière, its inventor). However, simply gauge, G or GA generally refers to Birmingham gauge. [1]
Gauge block, a metal or ceramic block of precisely known dimension, used in measuring; Sight glass, also known as a water gauge, for measuring liquid level heights in storage tanks and pressure vessels; Boost gauge, a gauge used in conjunction with turbo-super-chargers; Pressure gauge or vacuum gauge, see pressure measurement
Hardened and ground plug gauge Replaceable thread and plug gauges. These gauges are referred to as plug gauges; they are used in the manner of a plug.They are generally assembled from standard parts, where the gauge portion is interchangeable with other gauge pieces (obtained from a set of pin type gauge blocks) and a body that uses the collet principle to hold the gauges firmly.
A stream gauge, streamgage or stream gauging station is a location used by hydrologists or environmental scientists to monitor and test terrestrial bodies of water. Hydrometric measurements of water level surface elevation (" stage ") and/or volumetric discharge (flow) are generally taken and observations of biota and water quality may also be ...
The gauge (in American English or more commonly referred to as bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) and other necessary parameter to define in general a smoothbore barrel (in difference of caliber what define a barrel with rifling and there cartridge).
Metric gauge block set, 112 pcs Another set with 8 pcs, 125 mm - 500 mm Trolley model. Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge ...
An ultrasonic thickness gauge is a measuring instrument for the non-destructive investigation of a material's thickness using ultrasonic waves. The usage of an ultrasonic thickness gauge for non-destructive testing to check material properties such as thickness measurement, is regular in all areas of industrial measurements.
