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
