The definitive bench micrometer, the Universal Supermicrometer (USM), offers the advantage of being 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 components such as shafts, bores, O-rings, or just about any ID/OD part. The USM digital bench micrometer can serve as both the heart of your in-house gage calibration needs and a high accuracy part inspection system.
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. Multi-axis measurement table available on Model 504
Variable Force - Ranging from -8 to +40 ozf [-226 to +1134 g]
Touch Screen Operator Interface - LCD touch screen computer can be positioned to accommodate each operator's needs.
GageCal® Control Software - Microsoft Windows® based software reduces data entry, eliminates transcription errors, and speeds up measurements of your digital Super Micrometer. GageCal automatically enters tolerances for rings, plugs, pins, threads (calculates pitch/major diameter) and flags out-of-tolerance conditions.
Two Point Calibration - Mastering with two, NIST traceable blocks, allows continuous, accurate measurement over the full direct reading range. This provides significantly higher levels of productivity when compared to single point comparators.
Flexible Fixturing - Pratt & Whitney's bi-directional probes (US Patent) and flat anvils are standard accessories. The bid-directional probes allow for both internal and external measurement without time consuming set-up changes. V-groove fixturing provides repeatable probe positioning.
