Engineering construction angle: light fluorescent blisters are clearly visible at night, enabling accurate horizontal and vertical calibrations. This multi functional angle tool supports reliable setup and alignment in low light conditions. Multipurpose magnetic angle: Uses a sensitivity bearing gravity dial to automatically measure a variety of slopes, with a transparency plate that provides a clearer view and precise slope angle readings. Multi functional magnet angle gauge: Easy and simple to operate, includes a back angle comparison table for quick reference, delivering convenient and efficient angle measurement for a range of tasks. Magnetic angle slope: Features a unique design scale dial for measuring slope angle, with transparency for clear reading and obvious, useful measurements. Use scenarios Construction sites and workshop setups: Align frames, scaffolds, forms, and equipment with clear night visibility and reliable angle readings. Carpentry, machining, and fabrication: Set bevels, calibrate machine angles, and ensure accurate angle references for cuts and fixtures. Landscaping and drainage planning: Measure and verify site slopes to achieve proper grading and water runoff.
