PRO 3600 Electronic Water Scale

Digital protractor - electronic water scale

About the PRO 3600 Electronic Water Scale

The PRO 3600 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 3600 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 PRO 3600 has an RS-232 compatible digital output which will interface with computers, data loggers and printers. This feature, along with the improved accuracy, higher resolution and simple operation, makes the PRO 3600 a benchmark tool for years to come.
