The Anglestar® Protractor System (APS) is a ready to use, stand alone system for angle measurements.

The system incorporates a special AccuStar I ratiometric electronic clinometer, a digital display, and a standard four foot cable. (Cable lengths up to 200 feet are available. Consult factory for details.)

This system will operate for over 1,000 hours on one 9 volt battery and may be powered from an external power source between 9 and 15 Vdc, drawing minimal current.

The display may be mounted up to 200 feet from the sensor, for remote sensing applications such as drilling equipment or tower crane overload protection.
