Pratt & Whitney External Supermicrometer® Model C

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.

• 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
• Carbine-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 um (0.000010 in.) increments for high resolution
