Mitutoyo Electronic Inside Hole Micrometers
With an LCD screen, these micrometers make it easy to read inside diameter measurements taken from cylinders and rings. Place the micrometer inside your bore, then turn the thimble until the spindle makes contact with both sides. For an accurate reading, stop turning as soon as you feel resistance on the thimble.
USB data cables (sold separately) connect micrometers directly to your PC.
10-pin data cables (sold separately) connect micrometers to a Mitutoyo miniprocessor or multiplexer.
Wireless data transmitters and receivers (sold separately) let you send data from micrometers to your PC without a cable.
