Rotur Inside/Outside Caliper

The Rotur inside/outside caliper is a must - have tool for accurate measurements. It can handle workpieces with a diameter of up to 7 inches. Its straight end is ideal for measuring the internal size of narrow items like vases and goblets. To obtain precise dimensions, just measure the exposed end while the other end stays in contact with the workpiece. For consistent measurements, you can lock the caliper's position by tightening the adjuster screw. The rounded ends of the caliper ensure that your workpiece won't get scratched. SKU: CIO7

Using this Rotur caliper is easy. First, check if your workpiece is within the 7 - inch diameter limit. If you're measuring the inside of a narrow object like a vase or goblet, use the straight end. Place one end in contact with the workpiece and measure the exposed end for accurate dimensions. When you need to take the same measurement multiple times, tighten the adjuster screw to lock the caliper's position. As for maintenance, keep it clean and dry. Avoid dropping it as it may affect its accuracy. And always store it in a safe place. Make sure to handle it gently, especially the rounded ends which are designed not to scratch your workpieces.
