2. Bore gauge - Wikipedia

   en.wikipedia.org/wiki/Bore_gauge

   An inside micrometer or vernier bore gauge measures a bore directly. The gauge has three symmetrical anvils that protrude from the gauge body that are connected to the dial or micrometer mechanism. As the knob is rotated it moves the anvils in or out with respect to the measurements.

3. Micrometer (device) - Wikipedia

   en.wikipedia.org/wiki/Micrometer_(device)

   Animation of a micrometer in use. The object being measured is in black. The measurement is 4.140 ± 0.005 mm. Micrometers use the screw to transform small distances [9] (that are too small to measure directly) into large rotations of the screw that are big enough to read from a scale. The accuracy of a micrometer derives from the accuracy of ...

4. Calipers - Wikipedia

   en.wikipedia.org/wiki/Calipers

   A caliper using a calibrated screw for measurement, rather than a slide, is called an external micrometer caliper gauge, a micrometer caliper or, more often, simply a micrometer. (Sometimes the term caliper, referring to any other type in this article, is held in contradistinction to micrometer.)

5. Gauge (instrument) - Wikipedia

   en.wikipedia.org/wiki/Gauge_(instrument)

   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 ...

6. List of measuring instruments - Wikipedia

   en.wikipedia.org/wiki/List_of_measuring_instruments

   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 ...

7. Hook gauge evaporimeter - Wikipedia

   en.wikipedia.org/wiki/Hook_gauge_evaporimeter

   The device consists of a sharp hook suspended from a micrometer cylinder, with the body of the device having arms which rest on the rim of a still well inside the pan. The still well serves to isolate the device from any ripples that might be present in the sample being measured, while allowing the water level to equalize.

8. Gauge block - Wikipedia

   en.wikipedia.org/wiki/Gauge_block

   In use, the blocks are stacked to make up a desired length (or height). Gauge blocks were invented in 1896 by Swedish machinist Carl Edvard Johansson. [1] They are used as a reference for the calibration of measuring equipment used in machine shops, such as micrometers, sine bars, calipers, and dial indicators (when used in an inspection role ...
