Description: A low cost version of a precision tool. A six inch model with a thumb wheel is recommended. Battery-powered digital read outs are not required. Battery-powered digital calipers have the disadvantage that they don't work when the battery is dead, which can happen when the caliper is stored unused in your toolbox.
Purpose: To measure parts to within 0.001 inch, usually to inspect or verify dimensions. We will use calipers to measure parts so that we can create accurate CAD models.
