Specification: Item Type: Vernier Caliper Material: Stainless Steel Resolution: 0.001inches / 0.02mm Accuracy: 0.0012inches / 0.0m Tooth Thickness Range (Horizontal Scale): 0-1.56inches (39.6mm) Chordal Thickness Range (Vertical Scale): 0-1.44inches (36.7mm) Instructions: 1. The chordal tooth thickness caliper measures the thickness of the gear tooth with the top circle as the measurement reference. 2. The chordal tooth thickness caliper has two movable vernier scales that are perpendicular to each other. There are two measuring jaws that measure the thickness of the string; the other is the "predetermined" string height. 3. Calculate the chord height and the chord tooth thickness based on the gear parameters. The caliper with the chord height is fixed in size and locked, and the fixed end of the chord height is placed against the top of the tooth, and then the two claws of the chord tooth thickness are ed to the two different side profiles, and the chord is measured. The teeth are thick. Package List: 1 x Vernier Caliper Package List 1 x Vernier Caliper
