Built for real jobs: IP54 dustandsplash protection means the digital protractor / angle ruler keeps working on dusty jobsites and in wet conditions where splashes are likely, so you can measure indoors or outdoors without losing functionality. Read measurements clearly in any light: the HOLD function freezes the current reading on the display and the threebutton backlight illuminates the screen for easy viewing in dim areas or at night, reducing rechecks and mistakes. Hands, more accurate measurements on metal: a strong magnetic base secures the tool to iron surfaces so you can take stable, repeatable angle readings on steel beams, pipes and other ferrous materials without needing a second person. Key benefits — why you need it Saves time and reduces errors by letting you freeze and read a stable measurement even in low light or awkward positions. Improves safety and efficiency by allowing hands attachment to metal workpieces so you can mark, cut or align without balancing the tool. Designed to stay reliable on jobsites where dust and occasional splashes are common. What it does and how it performs Function: digital protractor / angle ruler for precise angle measurement. Visibility: threebutton backlight plus HOLD function for clear readings in dark or confined spaces. Durability: IP54rated protection against dust intrusion and water splashes. Compatibility: magnetic base adheres to iron and other ferrous surfaces for secure, hands use. Practical use scenarios Metal fabrication: attach the protractor magnetically to a steel bracket or beam to check or transfer angles during fitting or welding. Plumbing and HVAC: secure to iron ductwork or pipe to measure and mark precise angles for cuts and connections. Outdoor construction/renovation: maintain accurate angle measurements on exposed trim, fences or metal framing in dusty or damp conditions. What you get A digital angle ruler that combines a visible display with HOLD and backlight controls, IP54 resistance for onsite durability, and a strong magnetic base for precise, hands measurements on ferrous materials. Designed to solve common onsite problems—poor visibility, unstable readings, and exposure to dust or splashes—this digital protractor provides reliable angle measurement where and when you need it.
