Universal Supermicrometer - 501,504 Upgrade

A Standard to Grow With

At Pratt & Whitney we’re committed to an ongoing development program that will produce a continuous stream of new or improved applications for the Universal Supermicrometer product line.  We’re equally sensitive to the investment one makes in such an instrument.  That’s why we make all new developments reverse compatible to the very first Universal Supermicrometer we shipped.
