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.
Features
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 high-grade magnifier.
With the illuminator attachment, the Comparator converts into a self-contained illuminated measuring magnifier.
Reticles (protected in a plastic case) are easily interchanged by a screw-in mount. Measures radii, diameters, angles, hole sizes, pitch and thicknesses.
This 7X comparator is widely used by machinists, toolmakers and inspectors in the industry.
