Carbon 200 mm Multifunctional Angle Measuring Set (Protractor/Angle Gauge/Caliper/Digital Protractor) Product Overview This 200 mm multifunctional carbon steel angle measuring set combines an angle gauge, protractor, caliper, digital protractor, and electronic protractor. Made of high-precision carbon steel, it is durable and suitable for machining, woodworking, architectural surveying and mapping, teaching, and other applications. It supports high-precision angle measurements (0-360°) and length/depth measurements (0-200 mm) to meet the needs of various industries. Product Features ✅ High-Precision Measurement The mechanical vernier protractor has an accuracy of ±0.1°, and the digital electronic protractor has an accuracy of ±0.05° and a resolution of 0.01°, ensuring accurate and reliable measurement data. Main ruler made of carbon steel with a scratch-resistant coating, wear-resistant and impact-resistant, ensuring long-term use without deformation. ✅ Multiple functions in one device Angle measurement: 0–180° (expandable to 360°), suitable for inclined planes, tapers, and slope detection. Length/depth measurement (caliper function): 0–200 mm, one ruler for multiple applications, saving on tooling costs. Digital display: High-resolution LCD screen, supports degree/radian switching, data hold function, zeroing function, easy to use. Applicable scenarios Machining: Form angle measurement, part assembly Woodworking/Furniture making: Chamfer angle measurement, mortise and tenon joint calibration Architecture/Engineering: Slope measurement, steel structure assembly
