In some circumstances it is crucial that the distances that are measured are accurate down to a very small degree, particularly when working with objects that must fit together smoothly with no gaps or cracks. The way to achieve these precise measurements is to use a digital calliper. Digital calipers not only take measurements on the outside and inside of objects they also measure the depth of holes and the height of steps. The advantage they give the user over traditional vernier calipers is the digital readout display that leaves you in no doubt what your measurement is.
An example of a reliable lower priced caliper is the Neiko digital caliper. The Neiko range is quite extensive and they make solid quality calipers that are suitable for both the home handyman and the professional.
The standard size that you will find a digital calliper in is 6 inches or 150mm. This size gives you a calliper that is comfortable to hold in your hand when taking a measurement and will fit nicely in the toolbox when you have finished using it. However, there are longer calipers available for those who prefer a larger hand tool. 8 inch and 12 inch calipers are not uncommon and they generally have the same size heads but are held by longer handles.
The digital readout is a fairly straightforward piece of technology with a couple of buttons to get your measurements displayed and to reset again once your measurement has been noted. You can set the absolute position of your calliper at any time and you might also have the option to change the readout from displaying the results in inches to a metric display.
When adding technology to traditionally simple tools you will have the problem of finding that the tool doesn’t work because of such things as a flat battery or a failure within the workings of the electronics. It’s always a good idea to keep a spare battery in the toolbox. As a backup system the digital calipers also provide you with the markings along the handle to take a measurement in the old-fashioned way.
