Digital protractor - electronic water scale

About the PRO 360 Electronic Water Scale

The PRO 360 series is a revolutionary measuring tool that provides an immediate, digital reading of all angles in a 360º circle. The machined aluminium frame is a rigid, lightweight, ultra-precise platform that allows the state-of-the-art sensor and its microprocessor circuit to provide unsurpassed accuracy throughout the Protractor’s 360º range.

The PRO 360 series uses an innovative liquid-filled angle sensor. As the protractor is moved, the liquid seeks a new position, resulting in changes in the electrical properties of the sensor. A microprocessor analyses the changes and calculates the numbers seen on the Display.The unit operates for up to 500 hours on a single 9 V battery.
