FIELD: measuring equipment. SUBSTANCE: device has body 1, eddy current pickup 2, including coil 3, conversion unit 4 and recording unit 5, hinge 6, rod 7 one end of which carries measuring tip 8, and the other end 9 is made as cone and installed in sensitivity zone of eddy current pickup 2. Device is to be mounted coaxially into hole of part 10 being measured. Measuring tip 8 is moved around the hole surface, and the size sought for and non-perpendicularity of hole axis to face surface are determined by signal of eddy current pickup 2. EFFECT: high efficiency of measurements. 2 cl, 1 dwg
