    Overview for SmartTool 09429606 Pro 360 Digital Measuring Protractor w/ Case

    The SmartTool Pro 360 Digital Measuring Protractor is a state-of-the-art device that measures and provides digital readings of all angles in a 360-degree range. The Pro 360 is a widely used measuring instrument in many fields and industries because of its accuracy and stability. 

    No More Second Thoughts: The Pro 360 gives accurate readings thanks to its patented, liquid-field sensor, a product of over three centuries of professional experience. Its accuracy of up to 0.1-degree accuracy and 0.1-degree resolution remains unmatched. 

    Work With Ease: Readings made with the Pro 360 are clearly shown on the LCD, which intelligently flips over whenever the unit is upside down. Built-in front panel buttons can capture readings and reset from zero to any angle for quick measurements. Another feature that makes using the Pro 360 so convenient is its simple recalibration capability. With this, users can reset accuracy to factory settings using available flat surfaces. 

    No-Hassle Calibration: Unlike other digital protractors that need to be returned to the manufacturer for recalibration, the Pro 360 can be calibrated to factory accuracy by users in just a couple of minutes using any flat surfaces on site. No special tools are required. 

    Certifications: The Pro 360 Protractor has passed tests for EMI and RFI compliance as part of testing for the CE Mark Declaration of Conformity. It is certified for light industrial environments and conforms to the requirements of the EN50082-1:1992 standard.

    Because of its proven precision and ease of use, this proudly USA-made digital protractor is widely used in various applications including but not limited to aircraft rotor angle measurement, aircraft leveling, racecar wing and chassis adjustment, wheel alignment, ADA measurements of ramps and handrails, industrial lathe and mill alignment, as well as hobbies like model railroading, woodworking, and metalworking. 

    Note: If you're looking to transfer your angle measurement data to a computer, check the Pro 3600 Digital Protractor.
