About This Product
Students use a vernier caliper to learn how a sliding vernier scale gives readings finer than the main scale, then apply it to measure the diameter of a rod, the inside of a tube or the depth of a hole. It is a standard tool for length measurement practicals in school physics and vocational workshops.
