Master Vernier Caliper # 123EM-12

123EM-12 Master Vernier Caliper: 0-12”/300mm

The 123EM-12 master vernier caliper has graduations of .001”/.02mm.

Ultimate example of slide caliper design. It is more accurate, has the easiest reading vernier style, is stronger and offered in much longer lengths than other slide calipers.

Readability Features:

• Long 50-division vernier scales permit half as many bar graduations as conventional single-vernier tools. These widely-spaced graduations make it easy to read to .001" or 0.02mm.
• 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 and lock nut holds measurements.

The 123EM-12 vernier caliper has an approximate jaw depth of 58mm.

Long-Life and Accuracy Features:

• Fine tool steel construction makes the jaws harder and longer-wearing than stainless tools. All tools through 24" (600mm) also have hardened and stabilized bars.
• Hardened, ground and lapped measuring surfaces
• Machine divided graduations for accuracy
• 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.
• Tools with inch and millimeter graduations on the same bar have outside readings only. (Inside readings 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
