If you can focus you can perform cost-saving, accurate measurements of surface damage to mechanical parts.

Damage to leading edges, props, rotors, shafts and other components can be measured in a matter of minutes, and courses of action quickly and economically determined.

Introducing the 8400K Digital Optical Micrometer. It lets you measure the width of scratches using the reticle eyepiece and 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.

Windshields and other transparent materials may be measured for overall thickness, depth of crazing, and depth and width of imbedded bubbles or seeds as well as scratches.

The 8400K was designed for use in the field. The sealed, non-magnetic case is dustproof and shock-resistant to withstand everyday shop use.

The hardwood instrument case also contains adapters and lenses for use on convex, concave, or any combination of these surfaces.

With the 8400K, damage can be measured optically in a fraction of the time needed for other methods such as "blend-out." Spending time on a part that may need replacement is costly, and in many cases, the 8400K can be used to inspect parts while on an aircraft, whereas removal is often necessary using other methods.

In addition to the clear LCD readout "floating zero" and other features, the 8400K's digital display also has a serial port for data export to an optional processor/printer.

The processor can print, organize and store statistical data and download to a computer via an RS232C cable, providing you with a hard copy history for certification of all sample measurements.

First, focus on a smooth surface next to a scratch. Then, zero out the digital display (you can choose a readout in either inches or millimeters). Next, focus on the bottom of the scratch. The digital display shows depth relative to the surface.
