NOTE — This is a comparator gage and must be set with a setting ring, micrometer, caliper, etc… You set the reference measurement using a micrometer, etc, by the rotating dial and locking it in place.  Subsequent measurements will show you variance from the reference.  In other words, this is not a direct reading gage and does not display an absolute measurement.  You obviously can use it to arrive at absolute measurements, it just takes a few steps and some arithmitic.  

Half-ball-type carbide measuring contacts.  


Inside dimension (ID) measurement capability for making comparison measurements of hole diameters and groove and tube thickness

Spring-loaded for point contact at constant measuring pressure

Dial display provides precise, readable measurements in metric units
