    The Fowler/Bowers XTD Electronic Holemikes are the new generation of the Fowler/Bowers bore micrometers. The XTD electronic holemike bore gages now have extended travel with fixed anvils. Operators no longer have to worry about switching out the anvils as in past generations. All XTD Electronic Holemikes come standard with a ratchet stop which ensures better repeatability among operators. The “two-button” electronics are easy to operate and have the capability of storing up to three preset sizes. The holemikes have RS-232 output and can be connected to a laptop or PC by cable (see below) or wirelessly.

    The 54-364-100 XTD Electronic Holemike Set comes with a 5-year warranty. These digital internal micrometers are manufactured in England by Bowers Metrology, one of the most respected bore gaging companies in the world. Top quality products usually come with a great warranty and the Fowler/Bowers XTD Electronic Holemikes are backed with the best warranty in the industry.
