1、, more accurate and more comprehensive than traditional models with bubble vials and single‑function measuring tools with protractor, angle finder and level gauge. 2、V‑groove base and backlight, the base with strong magnets can be firmly fixed on curved or cylindrical magnetic surfaces, and the measured values displayed by the backlight in dark conditions are still clearly visible. 3、A wide range of applications, it is suitable for automotive, wood and machinery industries, machinery, medical fields, construction, drilling machinery, masonry, etc. 4、Support angle unit conversion: 4 x 90°m/m: 1000mm/m, %: , in/ft: 12in/ft. For conventional absolute value, this tool also has a relative measurement mode, which can quickly measure the angle between two measured surfaces. 5、 and , with a size, it is easy to carry and use with other measurement tools, and expand the measurement range, compact and affordable.
