A digital caliper makes measurement easy and accurate. Simply place the object to be measured between the caliper's jaws and the digital reading will give you an accurate measurement - you won't have to strain your eyes to see the tiny line markings of the ruler.

The digital caliper can be reset to "0" at any position, the measurements can be switched between metric and inches, and with data output interface, data can be input to a special printer or a computer via special cable for data processing and printing. It also has data holding, fast display, fast tracing max and min value during measurements, conversion between relative and absolute measurement and tolerance zone setting.
