The Standard of Accuracy - Pratt & Whitney

UNIVERSALMEASURINGSYSTEMLABMASTER ®The Standard of AccuracyLaser-BasedLABMASTER ® is designed to provide the ultimate inuser-friendly operation while delivering calibration-qualityaccuracy and reproducibility. Our exclusive digital interferometermeasures internal and external dimensions bycomparing the measurement probe position to the wavelengthof a laser light source, effectively coupling thewavelength of light to the part being measured. Ourpatented laser path is in line with the measurement axisto eliminate Abbe error.The thermal coeffi cient of expansion for this laserwavelength is more than ten times smaller than that of steel,making for a highly stable measurement source. Equallyimportant, the linearity errors inherent in other scales(glass, steel, LVDT’s) are absent in Pratt & Whitney’s laser.Because this wavelength of light is stable, linear, andhas very high resolution, when compared to like instruments,LABMASTER ® provides the most accurate meansof linear dimension measurement available in the world. Andthat’s not all.To further minimize instrument error, precision forcesystems guide our exclusive bi-directional probes andassociated optics along very accurate air-bearing slides. Alarge, variable-attitude work table accommodates a growingfamily of fi xtures to precisely hold your gages and parts.GageCal , our own Windows ® -based control softwaresimplifi es data collection and speeds up data entry. Add ouroptional gage management module and the system iscomplete; with all subsystems complementing each otherto deliver the accuracy of a comparator while offering theproductivity associated with direct-reading instruments.Simple, Flexible and FastEnglish or metric measurement of rings, plugs, pins,threaded plugs, gage blocks, length standards, threadedrings, calipers, and just about any precision part, is accomplishedin virtually no time at all. This speed advantagecomes from our exclusive bi-directional probes, integratedlocating posts to locate parts on the measuring table, and awide direct reading range.To use, master the instrument with the following twostep technique. First place a laboratory grade gage block,traceable to the National Institute of Standards and Technology(NIST), against the integrated locating posts and close thebi-directional probes. Once engaged, key in the value of theblock. Next, open the probes and replace the gage blockwith another larger gage block. Again close the bi-directionalprobes and key in the value of the block. The systemis now calibrated throughout the range of the two blocks.Using different size gage blocks allows the user to vary thesize of the range to meet specifi c needs.Now that the system is calibrated, any external dimensionspecimen that falls within the calibrated range can beplaced between the bi-directional probes. Once the probesare closed on the specimen, the absolute measurement,traceable to NIST, will be displayed. That’s all there is to it.To switch to internal measurement, reset the datum bypositioning a NIST traceable ID master over the probes,open the probes and key in the new internal datum.With no hooked feelers or jaws to compromise accuracy,and no levers to adjust when changing direction, youspend your time measuring, not setting up! Changingbetween inch or metric happens with the touch of a button.A Standard to Grow WithAt Pratt & Whitney we’re committed to an ongoingdevelopment program, that will produce a continuousstream of new or improved applications for the LABMASTER ®product line. We’re equally sensitive to the investment onemakes in such an instrument. That’s why we make all newdevelopments reverse compatible to the very fi rst Labmasterwe shipped. So when you purchase a Labmastertoday, be assured that your investment is safe. Becauseas your measurement needs evolve-and they will-yourLABMASTER ® and Pratt & Whitney will be there ready toaccommodate your new measurement needs.Guaranteed Service/A2LA AccreditedThe LABMASTER ® was designed with serviceabilityin mind.
