If you're looking for a direct-reading metrology instrument and an electronic size comparator for use on the production floor. Look no further – the third-generation External Supermicrometer® provides durability, digital accuracy, speed of measurement, and range of applications. The Super Micrometer comes in four models of varying length capacities. Custom Super Micrometers of up to a 40 in. (1000 mm) measuring range are available upon request.
LabMaster Standard® (U306617) is laser-interferometer-based for ultimate accuracy.
Our exclusive digital interferometer measures the dimension of the specimen by comparing the measurement probe position to the wavelength of a HeNe laser light source, effectively coupling the wavelength of light to the part being measured. Our patented laser path is in-line with the measurement axis to eliminate Abbe offset error.
The LabMaster Standard has the advantage of having two instruments in one, a direct reading instrument and it can be used as a gage block comparator.
Pratt & Whitney LabMaster Universal® Measuring System
With instrument uncertainty to 2 millionths of an inch (50 nanometers), the Labmaster Universal (LM U306270) is suitable for virtually all Internal (ID) and external (OD) measuring applications. This laser-based universal length measuring system (ULM) has been developed by Pratt & Whitney for gage calibration laboratories that need to precisely measure length, outside diameter, inside diameter, pitch diameter, lead, major/minor diameter, taper, linear displacement, and thickness.
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 parts 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.
