About This Product
Students switch the caliper on, close the jaws gently and press zero, then measure the outside diameter, thickness or length of an object, or the inside diameter of tubes and rings. The reading appears directly on the LCD with no vernier-scale interpretation, and the zero button allows relative measurements from any position. The caliper is kept in its storage case after use. Besides buyers across India, the Digital Vernier Caliper can be exported to institutions in Slovenia, Eritrea, Australia, Honduras, Saudi Arabia and Antigua and Barbuda.
