Fowler-Bowers line of external micrometer frames can ONLY be used with the Fowler-Bowers Superbore System. Data is read on a Sylvac Digital Indication Unit in inch or metric, resolution to .0001", .00001" or .001mm, .0001mm. Allows absolute or comparative measurements. The frames serve as snap gages with the quick action lever on the transducer. Its design allows one-hand operation, and spring loading ensures correct measuring force at all times; there's no "operator feel" to interfere with accuracy. One transducer/handle fits all sizes and quickly interchanges the frames as needed. The 6' cable allows use at the machine or inspection center.
