Pratt & Whitney External Supermicrometer® Model C

A direct-reading metrology instrument and an electronic size comparator for use on the production floor. The External Supermicrometer® provides durability, digital accuracy, speed of measurement applicable to a range of applications.

Features & Benefits of the External Supermicrometer®

Heavy-duty cylindrical bed
Chromium-plated cylinder ensures long life and performance integrity and the rack and pinion drive eliminates movement during the measuring cycle
Adjustable pressure tailstock
Exclusive Electrolimit® tailstock offers adjustable pressure from 50 to 1350 g (2 to 48 ounces) for reliability and optimum performance
Carbide-tipped measuring spindles
Non-rotating measuring spindles have long life, corrosion-free lapped anvils and are calibrated to ultra finish and precision
Elevating table
Adjustability allows for presentation of the part to the instrument in a non-influencing manner
Direct-reading, microprocessor-based digital display
Easy-to-read digital display provides direct reading in inch or metric units
Calibrated analog meter
Establishes the reference zero for taking direct measurements from the microprocessor-based digital display
Digital module
Divides the measurement into 0.25 µm (0.000010 in.) increments for high resolution
