The invention relates to a dial measurement gauge, which comprises a drive rack with a transmission multiplier mechanism connected to a movable pointer of its dial, a depth feeler gauge movable along and opposite the toothing of the rack, and a device for the protection of the said toothing. The gauge is characterized by the fact that the rack is formed by the rigid assembly of two profiled members, one of which comprises the toothing and the other covers the exposed side of the said toothing at least over its entire length and bears, with free sliding motion, against the depth feeler gauge located opposite it.
