The 8400K Digital Optical Micrometer lets you measure the vertical depth of surface features, usually to evaluate the severity of mechanical damage such as scratches, corrosion, pits or blemishes difficult to observe by other methods. The micrometer optically measures the depth, or difference in height, of one surface to another. Focus sharply on a good surface near a scratch or pit and set display to "0.0000", then carefully focus into bottom of scratch or pit and read depth on digital display.

More Information
Microset Surface Replication Kit - Many grades are offered instead of just one grade. Microset offers 12 standard grades; four for aerospace and industrial and eight for nuclear. Custom compounds offered as well. (Cure times, viscosity and color are the most common variables in that order.)
An advanced delivery system is provided, not just “a stick and a scrap of cardboard”. Microset offers delivery systems for industrial, not dental applications. The dispensing guns use custom mixing nozzles, with 32 instead of 24 “folds”, because complete mixing is critical. Other products are mixed by hand with a “stick on piece of cardboard”.
Microset represents itself as a strictly industrial and not dental compound. The phrase: “for replication of metal surfaces” is printed on Microset cartridges and the website shows industrial applications ONLY; with no dental context or reference whatsoever. • The U.S. Department of Energy (DOE) funded a study citing desirable properties of Microset. The DOE funded a study on engine wear and friction that featured the use of Microset to examine bearing surfaces. This report cites the ideal industrial replication characteristics of Microset compounds.
Microset compounds are engineered to leave no harmful residues on specimens under study. Some replication compounds contain harmful chemicals that can damage the specimen under study. Over the years, Microset has worked closely with the nuclear industry and has removed undesirable elements and fillers. Some chemicals which are still present by necessity have been reduced to minimal or trace levels, as dictated by customer requirements.
Microset has eliminated “clear surface layer” issues that can compromise accurate analysis. Microset compounds are designed for macro and micro (sub-micron) microscopic examination. As a result, they exhibit no clear or translucent surface layer. Products which do exhibit a clear-layer effect are problematic because it is difficult to determine whether a microscope is focused on the top or bottom of the ambiguous clear layer.
