3 Overview

Tire tread depth gauge (hereinafter referred to as "depth gauge") is measured using the depth measuring rod groove depth gauge Device for measuring vehicle tire crown tread depth, depth gauge by reading into the form of Vernier depth gauge (see Fig. 1) with a number of explicit depth gauge (see Figure 2) categories. Vernier depth gauge is the use of the principle of vernier scale box measuring surface and relative movement of ruler measuring faces separated by distance Reading measuring instruments; digital display is the use of grating depth gauge or measuring magnetic grid measurement, digital display principle of the foot frame Measuring surface and relative movement of ruler measuring faces separated by a distance measuring instrument readings.
