FIELD: measurement.
SUBSTANCE: device for inspection of holes of parts relates to control and measurement equipment and can be used for control of holes of parts, in particular, internal surfaces of pipes, channels of smooth-bore and rifled arms. Device for monitoring holes of parts consists of a light source, a collimator, a circular optical mark former, a circular marking projector and a photodetector connected to the control unit, is made in a single housing in the form of a measuring probe, and before controlled part positioning limb, annular gauge and unit for monitoring position of measuring probe relative to movement direction of part by movement unit are located. Control unit is also connected with controlled part movement unit and measuring probe position monitoring unit.
EFFECT: technical result is increased accuracy of measurements.
