Slant 200 protractor with rotating double scale

Rotating dual measuring roller. For measuring angles and slopes with one hand.

TO MEASURE AN ANGLE OR SLOPE:

1. place the base of the SLANT on the same plane as the surfaces to be measured.

2. rotate the thumbscrew knob until the bubble in the liquid container centres between the alignment lines, then read the angle and slope calibration marks on the pointer needle.

3. to measure a descent, reverse the SLANT.

TO SET AN ANGLE OR INCLINATION:

1. rotate the thumbscrew knob until the pointer needle comes to the mark for the desired angle or inclination calibration.

2. place the bottom of the SLANT on the same level as the surface that needs to be set.

3. rotate together until the bubble in the fluid container centres between the alignment lines.
