In addition to combination square sets, bevel protractors, and protractor and depth gauges, it is possible to buy digital protractors and other angle gauges.
A digital protractor is a type of protractor which measures the angle automatically without the user having to read it from a scale.
These protractors have a digital display which shows the angle on the screen.
Some of these resemble a bevel protractor, but other types of digital protractor do exist. Some of these resemble a small box in design (as seen to the left), and are placed on a surface to determine its angle.
These kind of tools may also be referred to as “digital angle gauges” or “digital inclinometers”.
