Precise angle measurement with an electronic level sensor for reliable level determination. Display resolution 0.05 deg for angles below 100 deg, and 0.1 deg for angles from 100 deg to 180 deg, with an accuracy of +/- 0.2 deg. Two measurement modes to meet different tasks: Absolute Measurement ABS and Relative Measurement REF. Clear backlit LCD display for easy reading in varying lighting conditions, providing instant, accurate measurements. Portable and easy to use: compact, lightweight digital protractor designed for hand held use in the field or workshop. Ideal for a range of applications including carpentry, construction, automotive construction, masonry and other projects requiring precise angle measurement. Use scenarios - Carpentry and cabinetry: align doors, windows, or trim and set precise miter angles for clean joints. - Construction and site work: verify floor or roof slopes, check level surfaces, and confirm angles on forms or scaffoldings. - Automotive construction and masonry: ensure correct component angles, joints, and alignment during fabrication or mortar work.
