320 Degree Universal Bevel Protractor Angle Gauge Vernier

Product Parameters:

1. Material: high carbon steel

2. Specification : 0-320 °

3. Measurement accuracy: 0.01

4. Structure of the all-purpose angle ruler: It consists of the ruler body, the straight ruler, the vernier, the slow motion device, the base ruler, the rectilinear scale, the locking nut and other components.

5. Applicable Scope: the interior exterior angles measurement in machining work

How to use:

      Users should calibrate the angle ruler to the zero position before the measurement, and the step won't be completed until the straight ruler and the rectilinear scale are well installed, the bottom edge of the straight ruler, the base ruler and the rectilinear scale fit seamlessly. After the ruler is calibrated to the zero position, users can use it to measure a angle in 0-320 ° by changing the positions of the base ruler, the rectilinear scale and the straight ruler.

Note: the all-purpose angle ruler should be assembled properly according to the angle to be measured before measuring workpieces.
