Moreover, it comes in a sleek protective case for added protection. A dial caliper is a measuring instrument with an accuracy rivaling that of a micrometer. For tools that could handle the elements, we checked the accuracy on some greasy, dirty fittings under the hood of an old project car. If daily verification of the caliper and periodic calibration are not conducted, the measurement may be questionable. Also, sliding the jaws open and grabbing a quick, accurate measurement was simple (thanks in part to that big display). Many find that their digital calipers are out of battery and have trouble reading the numbers on the LCD.
