Turn a 6-inch caliper into a protractor with the Angle Master Pro 6i. Clamped to the caliper’s jaws, the product determines or creates angles to within 1 minute of a degree, the company says. To measure an unknown angle, position the product in or around the angle, and then in the user’s guide look up the caliper reading. To set a desired angle, look up the angle and its corresponding caliper reading in the user’s guide, and then set the caliper to that reading.
