Pratt & Whitney ® Measurement Systems, Inc.

The Standard of Accuracy Two Instruments in One The Universal Supermicrometer™ represents an evolutionary leap forward in what many users consider to be the definitive bench micrometer. It offers the advantage of two instruments in one by providing the ability to measure both internal and external parts, gages, or standards. Additionally, as a high precision, direct-reading metrology instrument, it is equally capable of checking critical parts on the shop floor or serving as the heart of your in-house calibration laboratory. As with all Pratt & Whitney® instruments, accuracy and performance begins...

Features Mechanical and Thermal Stability A rugged cast iron base and thermally stable composite materials insure repeatable and reproducible results. Linear Encoder with Zero Abbe Offset A high precision glass scale located along the measurement axis eliminates Abbe offset errors that reduce overall measurement uncertainty. “Variable Attitude” Measurement Table Vertical table adjustment is provided on all instruments (model 501 and model 504). An optional, four-axis, measurement table allows additional adjustments in centering, swiveling and tilting (model 504). Variable Force Allows the Universal...
