SQUAREMASTER™

CONTOUREADER™

PMC SquareMaster Inspection InstrumentSquareMaster Inspection Instrument

The SquareMaster™ can increase your inspection accuracy while lowering your inspection cost. 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.

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.

PMC ContouReader metrology equipmentContouReader & Recorder Dimensional Metrology Equipment

The ContouReader™ by PMC Lone Star is part of a new generation of precision metrology equipment 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™ dimensional metrology 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.
