Fowler’s Pocket Optical Comparator magnifies images which are sharp, undistorted and free of aberrations. Convenient for checking angles, thread measurements, hole sizes and more. This 7X comparator is widely used by machinists, toolmakers and inspectors in the industry.
Scales are photo-etched into a glass reticle which is placed in actual contact with the measured object, thus obtaining simultaneous enlarged images of the scale. Used also as a highgrade magnifier.
Reticles are easily interchanged by a screw-in mount. Use them to measure radii, diameters, angles, pitch and thicknesses.
With the illuminator attachment, the Comparator converts into a self-contained illuminated measuring magnifier.
Comes with 5 reticles: 1, 5, 7, 8 and 13. Reticle No. 13, (not pictured), it is similar to #8 but in inches with 0-8", .0025", .005" graduations
