Dial Calipers:

Dial Calipers are a ubiquitous tool in the engineering community and are designed for precision. Precision is a necessity in measuring tools, but dial calipers take the product to the next level. The dial that causes the jaws to separate is located precisely where the thumb rests when holding the tool comfortably. This ergonomic design makes this measuring tool more appealing than others. Additionally, the dial caliper’s dual-jaw design can be used to measure an object’s outside dimensions and a feature’s inside dimensions. It is multi-functional, but also sleek, and easy to use.
