Digital calipers have become the more and more popular measuring
instruments for sizing lumber. It is easier for us to read sizes
directly from the numeric display. Moreover, the calipers can
display sizes in both English and metric units. The striking
advantage of digital calipers is that they have a data port to
output digital information to external devices.Therefore, many
commercial lumbersize-control software programs use this feature
to interface with their proprietary data-collection devices.
