Motionics Bluetooth Digital Protractor is an economic digital protractor with built-in Bluetooth Low Energy technology. It covers the whole 360° (4x90°) range with 0.05° resolution and 0.2° accuracy. Thanks to its wireless data transmission feature, protractor readings can be easily read out in real time on the screen of a smart phone/tablet/Windows PC remotely and from any angle.

BPRO comes in two form factors, as a cube or as a torpedo level, for different applications. Strong magnets on the solid military grade alloy body allow user to easily attach the protractor to any steel surface for measurement.

Our powerful measurement reading software, MultiGage, makes this Bluetooth protractor a more effective tool, allowing the user to read measurements from multiple devices at once, either continuously or in single capture mode with the press of a button. Additionally, there are many more innovative features in the app, such as an analog probe meter, cloud data streaming, a custom calculator, and so on, to make dimensional measurement faster and easier.
