Dedicated to measuring depth of hole/groove, and step of dies, etc.It is a dedicated instrument for measuring the difference in level and depth of the work piece in handy. The bottom surface of the base is brought into close contact with the measurement origin (zero point). Then the outer frame by rotating to align the zero position (to secure the outer frame by a clamp at that time). The amount that the probe was protruding from its position is read by the hour hand and minute hand. There are two types of analog and digital. Shape and the base of the size of the probe is also supported by the application. In response to the depth of the measurement section, stroke has each standard model of 10mm / 20mm / 30mm. To attach the connecting legs, you can compare and measure the depth of up to 220 ~ 240 mm by performing a reference point alignment using a block gauge. Download Catalog
