    Overview for SmartTool 9429598 Pro 3600 Digital Measuring Protractor w/ Case

    The SmartTool Pro 3600 Digital Measuring Protractor is a sophisticated, high-precision digital protractor that measures angles in all 360 degrees. It is accurate to up to 0.05° and has an RS-232 port for interfacing with a computer for angle measurement data transfers.

    Eliminate Guesswork: At the heart of the Pro 3600 is SmartTools’ patented custom sensor inclinometer that reads measurements at up to 0.05° accuracy and 0.01° resolution, ensuring quality work for any application.

    Measure with Ease: Taking accurate measurements with the Pro 3600 Digital Protractor is as fast as pressing buttons on the front panel. It has a “HOLD” button that “freezes” and lets you store the last reading taken and an “Alternate Reference” (Alt Zero) feature that lets you set a new reference point for 0.00°. Readings made with the Pro 3600 are clearly shown on the LCD, which intelligently flips over whenever the unit is upside down. The Pro 3600 has a lightweight and durable aluminum frame with grooves and threaded holes on the bottom for attaching to magnetic bases (not included) or any custom attachment.

    No-Hassle Calibration: Unlike other digital protractors that need to be returned to the manufacturer for recalibration, the Pro 3600 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 3600 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.
