The Baseline Absolute Axis 360 degree Goniometer features an integrated design for true vertical and horizontal levels built right into the goniometer. Easy to read with clear bubbles set in a yellow fluid, the levels function similarly to a carpenter's level, with black demarcations serving to mark level in both directions.
Marked off in 1-degree increments going in both directions, the full-circle head has 3 different scales calibrated to be used in the ISOM (International Standard of Measurement, STFR) system. The clear plastic design allows for easy observation of joints behind the goniometer, and one of the arms is also marked off for convenient measurement as a ruler in both inches and centimeters.
