Pocket comparator

A Pocket comparator is an optical device for measuring and inspection comprising a loupe and a reticle. The instrument was developed and manufactured by the Bell & Howell Company, but similar instruments of other names are made by other manufacturers.

It is used for:

  • Linear measurements in fractions of an inch.
  • Circular measurements in fractions of an inch.
  • Radius measurements.
  • Angle measurements.
  • Narrow line width measurements.
  • Circular measurements in decimals of an inch.
  • Linear measurements in inches.
  • Linear measurements in millimeters

    • Measurements are performed by bringing the surface of the reticle as close as possible to the work inspected.
