The Insize 2171-250 Digital Protractor is a precision tool ideal for measuring angles in engineering, woodworking, machining, and other applications. Its durable 10-inch blade is crafted from stainless steel and aluminum for longevity and reliability.
With a full 360° measurement range, a resolution of 0.05°, and an accuracy of ±0.15°, this protractor ensures precise results. The device features a user-friendly digital LCD display for clear readings. Functionalities include zero-setting, hold (to retain the current reading), and absolute/incremental measurement modes.
The locking screw allows for fixed angle measurements in specific ranges, while its removal enables a full 360° motion. Additionally, a built-in level vial assists in horizontal alignment. Powered by a CR2032 battery, the protractor is equipped with an auto power-off function for energy efficiency and comes with a protective storage case.
