For precise linear measurements consider the Origin Digital Caliper from iGaging which uses ABSOLUTE memory technology and also has USB data output. It keeps track of its origin position once set. Whenever the digital caliper is turned on, the easy-to-read large LCD displays the actual sensor position ready to start measuring. It's not necessary to reset zero and the measuring speed is unlimited.
This quality caliper competes directly with the top name brands with SPC output, but costs about $100.00 less.
