Digital protractor, 360° digital spirit level

【Multifunctional Goniometer】: The protractor features metric (mm) and imperial (inch) graduations and a precise digital display, allowing you to measure angles and lengths. The horizontal and vertical bubble level facilitates checking and calibration (note: the LED display does not provide the measurement; it is only used for angle determination).

[High Accuracy]: The digital goniometer measures internal, external, and opposite angles across the entire range of 0 to 360°. The measurement accuracy is ±0.5° and the resolution is 0.05°. You can switch between degrees and minutes to improve measurement accuracy and meet your various needs.

[Data Hold]: Press the hold button at any time to memorize the angle and efficiently save its value. The angle lock function maintains the desired accuracy and is suitable for woodworking, construction, or technical drawing. [Long Battery Life]: Super endurance, can operate continuously for over 2,000 hours. The digital goniometer automatically shuts off to save power and extend battery life. The protractor is equipped with a large LED for easy reading. [Multiple Applications]: This angle measuring instrument is often used in woodworking, architectural decoration, schools, DIY projects, machining, and other fields (including setting saw blade angles).
