See How The SquareMaster® Can Increase Your Inspection Accuracy While Lowering Inspection Cost.

The squareness, straightness or parallelism of what you manufacture is too important to be left up to guesswork. Conventional hand gages can't approach the repeatable accuracy and long life of the SquareMaster by PMC Lonestar.

± 0.000050 Accuracy
The SquareMaster can measure with an accuracy of ± 0.000050 of an inch (50 millionths) over any 12" of specified range. No hand gage even comes close.

It's our solid laboratory-grade granite master column that makes it possible. In fact, the SquareMaster is the only vertical squareness gage that uses a granite column. Besides unmatched accuracy, the SquareMaster's column requires only an occasional wipe-down with alcohol to keep it accurate for many years to come. That's why the SquareMaster is truly an investment sure to pay off in increased accuracy far into the future.

The SquareMaster can be used for virtually any measurement of straightness, squareness or parallelism on interior or exterior surfaces. Its precision direct dial readout substitutes reliable and repeatable results for the subjective calculations you probably now make.

Portable
The SquareMaster's lightweight design makes it completely portable for use on machine tables, surface plates, at production set-ups and many other locations. Use it for in-process work or in the Inspection Department for 100% inspection. Wherever you use it, SquareMaster will deliver unarguable results time after time.

The SquareMaster is available in two models with vertical travel up to 18"

Master Column
Made of laboratory-grade precision granite, straight and parallel within ± 0.000025 (25 millionths) of an inch per foot, treated with special lifetime dry lubricants.

Accuracy
To ± 0.000050" (50 millionths) over any specified 12" travel.

Measuring Range
VSQ-12 - 0" to 12" standard, 18" with extension bracket
VSQ-18 - 0" to 18" standard, 24" with extension bracket

Dimensions and Weight
VSQ-12 - 22" high, 8" square base, 28 lbs.
VSQ-18 - 30" high, 9" square base, 40 lbs.

Indicator Posts
Two steps -
7/32" diameter (.219" + .000")
                                  (- .003")
3/8" diameter   (.375" + .000")
                                  (- .003")

Extension Bracket
Your SquareMaster is shipped with an extension bracket as standard. It allows a second dial indicator (optional) to be used for increasing the continuous measurement range. The bracket can be rotated to check adjacent surfaces and around corners.

SquareMaster Accessories
Frequent calibration of the SquareMaster will keep it operating accurately for many years. By using the Master Square of laboratory-grade, lapped black granite, your measurements can be relied on without question.

*  PMC Contoureader




The ContouReader by PMC Lonestar is part of a new generation of precision instruments to inspect both internal and external dimensions of literally thousands of parts to guarantee the quality of your products. We offer two versions of the ContouReader; a standard and new Windows-based computerized version. The ContouReader inspects everything from dimples on golf balls to turbine blades with the same repeatable accuracy to reveal any defects, deviation from specifications, or rough edges that can adversely affect product quality.

The operation of the ContouReader is simple. A part is placed in a fixture, and the tracing stylus moves gently over the surface of the part, transferring the stylus arm movements into electrical voltages which are amplified and transmitted to the chart recorder or computer display. The recorder moves a pen to draw an exact duplicate of the part contour on chart paper up to 200 times its original size, and with accuracy of ±0.0002 inches on the standardized version. The computerized version will display an exact duplication of the part contour to an infinite magnification. A manual or electronic master overlay is used over the ContouReader tracing to compare for accuracy.

What will you be able to see? Crest forms, root radii, flank angles, pitch diameters, and others, all in seconds on a permanent record strip chart or electronically. The electronic version can be shared via DXF or DWG format.
