Model : AG-82201B

This 3-in-1 digital protractor uses angle sensor technology to calculate exact angles simply by tilting it to the desired angle. The LCD that provides reading that is always displayed in upright position in any angle. It measure angles within 4 x 90° (0~360°) range. Placing the meter on reference surface zero to measure relative angle gives measured angle result within 0.1° accuracy. It also has Absolute Angle Measurement to test whether the working surface is on the level to check roof slopes, wheel alignment, etc. With simple self calibration no other fixtures is needed.

The V-Groove ensures it sits flat against any metal surface (such as miter, table saws, etc.), round objects, curved surfaces or cylinders such as pipes, shafts or rods while the 2 powerful magnets on bottom plate for secures the attachment. With care you can also use it on aluminum or wood.
