Optical Comparators are inspection machines that project magnified images of parts onto a glass screen using illumination sources, lenses and mirrors for the primary purpose of making 2-D measurements.
Using an Optical Comparator allows the technician to see the part from the magnified form up to 50 times the actual size.
Very small radii and other featured can be easily checked when enlarged on the screen. Including thread gages, thread standards and specialized tooling.
This saves time, money and will ensure your gages meet specific federal guidelines.

Be prepared and stay ahead of the game. Have your scales calibrated by a service company or agent that is registered with the State of Agriculture, this this will ensure accurate measurement and prevent device malfunction. The service agent will provide you with a calibration certification that states it is in accordance to the specific requirements for WA State.
