STARRETT Master Vernier Calipers 123 SERIES LARGE NR
THIS CALIPER MEASURES APPROXIMATELY 17" IN LENGTH
This vernier caliper is the ultimate example
of slide caliper design.It is more accurate,
has the easiest reading vernier style,is
stronger and is offered in much longer
lengths than other slide calipers.
Readability Features * Long 50-division vernier scales, made
popular by Starrett. This feature permits
just half as many bar graduations asconventional single-vernier tools.These widely-spaced graduations makepossible easy reading to .001 or0.02mm without requiring a magnifyingglass* Flush fitting of the vernier scales tothe main scale means that these are inthe same plane, which eliminatesparallax. Vernier scales are adjustable* The open-face design of the slide allowsboth the inside and outside vernier scaleon the same side, thus allowing bothverniers to be read without turning thetool over* Black lines and figures against theStarrett satin chrome finish makereading a pleasure, not an effort* Screw-type adjusting nut allows for finemeasuring adjustments* Lock nut to hold measurements
Long-Life and Accuracy Features
* These tools are made of the finest toolsteel. This makes the jaws harder andlonger-wearing than stainless tools. Alltools through 24 (600mm) also havehardened and stabilized bars* Measuring surfaces are hardened,ground and lapped to close limits* All graduations are machine divided foraccuracy, not photo-engraved. They arealso deeper and sharper* The combination straight and angularways on the master bar allow forpositive alignment of graduations andeasy adjustment of the flush-fittingverniers* Sizes through 24 have divider points onthe back side to accurately set dividersand trammels as needed* Tools with inch and millimetergraduations on the same bar haveoutside readings only. (Inside readingsmust be compensated for by adding thenib width to the indicated reading.)* The longer length of the adjusting jawslide provides a longer bearing surfaceon the master bar, ensuring squarenesswith the solid jaw and extra resistanceto springing* Tight, smoothly fitted slides formaximum accuracy and easyadjustment
