The digital protractor is revolutionary measuring too to build 0.1 degree accuracy at vertical and horizontal planes and 0.2 degree accuracy at other angles.

The stainless steel frame with integral base-plane is a light, rigid and ultra-precise platform allowing the state-of-art sensor and microprocessor circuit to provide unsurpassed accuracy throughout the protractor's 360 degree range.

The front panel buttons can be used to capture desired readings or to designate an alternate reference surface from which subsequent angles are then measured. The unit can also be easily recalibrated in any available flat surface.
