Bluetooth Digital Protractor

Product ID:
$ 300.00

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. The protractor will turn off automatically after five minutes if the reading has not changed.

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.

The Bluetooth digital protractor works with MultiGage, our free cross-platform software that lets you read and record measurements wirelessly on your iPad, iPhone, Android device, or Windows PC.
