1. PRECISION This Vernier caliper delivers the ultimate marking precision. The Vernier scale and main scale slide smoothly within the main body for items to fit exactly. It has a finer minimum measurement than standard Vernier calipers, with a resolution of 0.05 mm (0.002 in) and a range up to 210 mm. 2. MULTIFUNCTION (MEASUREMENT AND MARKING) Five practical functions in one tool: measure 45-degree and 90-degree angles, depth, width, and use the main scale to mark lines. You can measure the thickness and depth of objects as with any caliper, and also verify angles with a combined miter and T-square. Use the main scale as a ruler to mark features directly on the workpiece for easier layout. 3. VERSATILITY AT ITS CORE This tool is highly versatile. It accepts a straight ruler that functions as a nonius/vernier caliper. It comes with an additional depth gauge, ideal for measuring cylindrical rods, tubes, and various angles. The depth stop is removable, and the caliper can be fully customized with extra bases to suit different projects. 4. EASY-TO-READ AND DURABLE Aluminum blades are milled with modern precision equipment, then ground and anodized for durability. The professional square-style ruler is built for long-lasting use. Scale markings are engraved in white on a black background for clear readability. 5. STABLE AND LIGHTWEIGHT The blade is made from anodized aluminum with a 2 mm thickness. The sturdy aluminum cast body is robust yet surprisingly light, about 30 g lighter than standard calipers. The lightweight, ergonomic housing reduces fatigue in the hand and wrist during extended measuring and marking. 6. USE CASES - Precision marking and layout on metal or wood for miters and square joints in cabinetry or fabrication. - Checking thickness and depth of rods, tubes, or hollow sections, and marking corresponding features. - Marking lines directly on workpieces by using the main scale as a ruler, or measuring and drafting angles for accurate cuts.
