Features V GROOVE MAGNETIC BASE: Digital angle gauge's magnetic V groove base can be firmly connected to black metal surfaces such as pipelines, steel structure frames, metal manufacturing, etc. ABSOLUTE AND RELATIVE MEASUREMENT: Digital angle finder has an absolute angle measurement function, which can test whether the working surface is on a horizontal plane to check roof slope, wheel alignment, etc. In addition, the magnetic horizontal plane can be used to check the relative angle between surfaces. LCD SCREEN: Digital protractor has a large backlit LCD screen. Regardless of the light, you can easily read the measurement results. When the electronic level is inverted, the displayed value will automatically reverse. When you arrive 0 ° or 90 °, sound are emitted through a beep sound.
