Labmaster Universal - Model 1000M

The Standard of Accuracy ...and the most popular instrument in industry!

With a 40 inch (1016mm) direct reading range and an 80 inch (2032mm) capacity with optional probes, this laser-based Universal Measuring System is designed for high accuracy, ID/OD/SD* gage calibration and part measuring.  Swivel, centering, tilt, and elevation knobs are all standard and easy to use.  Features include laser interferometer, computer control, air bearings, bi-directional probes, constant 

measuring force, and flexible fixturing.  These features offer guaranteed repeatability and operator independent reproducibility with unmatched speed.

With appropriate accessories, the LABMASTER Universal 1000M is capable of measuring rings (threaded & non-threaded), gage blocks, plugs (threaded & non-threaded), dial/test indicators, gage wires, micrometer heads, pin gages, tapered plugs (threaded & non-threaded), end standards, micrometers, and snap gages, all with NIST traceability.  Only a handful of traceable masters, such as blocks, rings, etc. are needed (not included).  The LABMASTER Universal 1000M can also measure a wide range of specialty applications such as ID/OD bearings (radial/axial clearance), balls, shafts, optics, as well as your precision parts.  The LABMASTER Universal 1000M includes a current model computer loaded with GageCal, Pratt & Whitney’s Windows based measurement and control software.  GageCal has predefined application screens and automatically enters tolerances for various types of measurements such as blocks, rings, plugs, and threads. P&W is accredited in accordance with the recognized International Standard ISO/IEC 17025:2005 by A2LA.
