3 Overview

Depth indicator is a measure of the depth dimension of blind holes, grooves and other measuring instruments. Depth indicator by the indicator, locking device, the base, and interchangeable spindle measuring class composition. Depth instruction sheet is divided into Analog and digital display depth indicator Depth indicator, its shape structure shown in Figure 1, Figure 2, may be accompanied by proof Gage, as shown in Figure 3. Figure 1 indicates the depth pointer table 1- pointer indicator; 2- locking device; 3- base; 4 - interchangeable measuring rod; 5- probe ......
