Starrett - Slide Calipers

Master Vernier Calipers - No. 123, 123M Series
Range: 0-72" (0-600mm)

Master Vernier Calipers - No. 123EM Series
Range:0-24" (0-600mm)

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 as conventional single-vernier tools. These widely-spaced graduations make possible easy reading to .001" or 0.02 mm without requiring a magnifying glass
  • Flush fitting of the vernier scales to the main scale means that these are in the same plane, which eliminates parallax. Vernier scales are adjustable
  • The open-face design of the slide allows both the inside and outside vernier scale on the same side, thus allowing both verniers to be read without turning the tool over
  • Black lines and figures against the Starrett satin chrome finish make reading a pleasure, not an effort
  • Screw-type adjusting nut allows for fine measuring adjustments
  • Lock nut to hold measurements

Long-Life and Accuracy Features

  •  These tools are made of the finest tool steel. This makes the jaws harder and longer-wearing than stainless tools. All tools through 24" (600 mm) also have hardened and stabilized bars
  • Measuring surfaces are hardened, ground and lapped to close limits
  • All graduations are machine divided for accuracy, not photo-engraved. They are also deeper and sharper
  • The combination straight and angular ways on the master bar allow for positive alignment of graduations and easy adjustment of the flush-fitting verniers
  • Sizes through 24" have divider points on the back side to accurately set dividers and trammels as needed
  • Tools with inch and millimeter graduations on the same bar have outside readings only. (Inside readinggggs must be compensated for by adding the nib width to the indicated reading.)
  • The longer length of the adjusting jaw slide provides a longer bearing surface on the master bar, ensuring squareness with the solid jaw and extra resistance to springing
  • Tight, smoothly fitted slides for maximum accuracy and easy adjustment
  • Made to rigid Starrett standards

NOTE: For inside measurements, the thickness of the nibs must be added to the caliper reading as follows:
