Another Sample Section (Procedure)

The pocket comparator is a small precision optical measuring instrument used for measuring small characteristics and/or dents, scratches, etc. on flat surfaces. The instrument is equipped with an etched linear scale, angular scale, and various hole sizes. The instrument is placed over the characteristic to be measured, the appropriate scale selected and the size is read directly from the etched scale. The instrument employs a magnification factor for ease of reading the various scales.
