Micrometer measures depth of surface features.
Digital Optical Micrometer, Model 8400K evaluates severity of mechanical damage such as scratches, corrosion pits, or blemishes that are difficult to observe by other methods. User focuses on good surface near scratch or pit, sets display to 0.0000 in., then focuses into bottom of scratch or pit and reads depth on digital display. RS232 serial port allows data export to included...
