Determining the fineness of a paint's grind is important, because too coarse a grind may reduce the paint's color uniformity, gloss, and opacity. [7] The Hegman gauge is widely used for this purpose because it requires minimal skill and only a few seconds' work.
The Calo tester, also known as a ball crater or coating thickness tester, is a simple and inexpensive piece of equipment used to measure the thickness of coatings.Coatings with thicknesses typically between 0.1 and 50 micrometres, such as physical vapor deposition (PVD) coatings or chemical vapor deposition (CVD) coatings, are used in many industries to improve the surface properties of tools ...
In the past, a common time measuring instrument was the sundial. Today, the usual measuring instruments for time are clocks and watches. For highly accurate measurement of time an atomic clock is used. Stopwatches are also used to measure time in some sports.
The ability to gauge thickness measurement without requiring access to both sides of the test piece, offers this technology a multitude of possible applications. Paint thickness gauges, ultrasonic coating thickness gauges, digital thickness gauges and many more options are available to test plastics, glass, ceramics, metal and other materials.
The wet film thickness will fall between the clearance of the shortest tab that is wet and the clearance of the next shortest dry tab. Dial indicator, also known as a dial test indicator, dial gauge, or probe indicator an instrument used to accurately measure small linear distances. Feeler gauge: a simple tool used to measure gap widths.

Various thin film characterization techniques can be used to measure the physical properties of PVD coatings, such as: Calo tester: coating thickness test; Nanoindentation: hardness test for thin-film coatings; Pin-on-disc tester: wear and friction coefficient test; Scratch tester: coating adhesion test
A density cup is an instrument that is used to ensure quality control in a paint or lacquer. [1] It does this by measuring the density of the paint or lacquer, and comparing this density with the density of a standard for that paint or lacquer. [ 2 ]
