Magnifying Comparators and Reticles

Magnifying Comparators and Reticles Case


This Magnifying Comparaor comes has many reticles options. You can use it just as you do any other scale - put it down on the work and measure. When things are small you have to magnify both them and the measuring scale in some way, and this is the most convenient and least expensive way to do it. An optical tool designed to take advantage of modern manufacturing methods to get accuracy, roughness, portability and versatility at an extremely low price.




  • Transparent Barrel Focusing Magnifier
  • Interchangeable Reticle (Transparent Scale)
  • Measure small dimensions accurately and conveniently.
  • Compare small shapes with established standards.
  • Do many similar jobs in new and unusual ways. More than 60 different reticles (transparent scales) are available. If you work with small objects or expect to do so, you need it in your tool kit. GUARANTEED. It is fully guaranteed.
  • Extreme Accuracy produced through newly-designed cameras which reproduce certified accurate scales on Reticles made of extremely tough, low expansion photographic film. Each Reticle is an original photograph. The accuracy is permanently built into the Reticle, and minor variations in the instrument do not affect it.
  • Can Be Positioned on Objects of Any Size. No depth-of-throat limitations with comparator.
  • Take it to the Work - Easily. You do not have to take the work to it as with larger tools making similar measurements. This results in important labor savings.
  • Many Reticle Patterns. Reticles for practically every use required in metalworking, measuring and comparing, as well as for other applications.
  • Only One Scale on a Reticle. Much easier to use because it is free from confusion of the user which results when many scales are crowded onto one Reticle.
  • Low Parallax. Reduces the spacing between work and scale to only .003" which prevents scratching yet practically eliminates parallax error.
  • Both Black-Line and White-Line Reticles. A unique feature is the supplying of the Reticles in pairs of the same pattern, one having black lines and one white lines, to insure contrast with the work being measured.
  • Needs No Special Light Source. Light is admitted through the transparent walls of the comparator to the object viewed. Any light adequate to inspect a part is adequate.
  • Also a High-Powered Magnifier. Without the Reticle, which is easily removed or interchanged, the Comparator becomes a high-powered magnifier, useful in many ways.
  • Pull-or-Twist Focusing. A unique construction that permits very quick focusing yet allows collapsing the instrument by a simple push when storing or carrying.
  • Quality Construction. Utilizes the best ground and polished glass lenses; the best plastics for the purpose regardless of cost; extra thick plastic for permanent rigidity; Reticles of special low-shrinkage plastic, bound in aluminum and stainless steel.
  • Small, Light and Rugged. A truly pocket instrument, as easily carried as a steel scale.
