High-quality 12-inch vernier caliper
This 12-inch vernier caliper is of high quality and is made of stainless steel, which is sturdy and durable. When not using it, I put it in a plastic bag packed with desiccant to prevent dust and moisture from entering. I use it to measure the inner and outer diameters of pipes. It has a high accuracy of 0.02mm and the measurement results are very accurate.
