4-inch Electronic Digital Vernier Caliper with Large LCD Screen

This caliper measures up to 6"or 100 mm.. It has a knurled lock clamp so you can fix it to the dimension you need. Whether you work in Imperial inches or metrics, one touch of a button allows you to switch between the two systems. Inches may be displayed decimally or fractionally. It measures thickness, internal width and depth. The display is large and bold on an LCD screen. Its adjustment wheel is on a precise ratchet system with knurled edges for easy grip. Battery life is maximized via an auto turn off function, because it is easy to forget to turn it off when you are busy. This is a critical instrument for an endless variety of applications.
