FIELD: instrumentation.
SUBSTANCE: device contains base, basing element with cone hole, indicator with measuring rod and clamp for pressing to the work surface. The clamp is secured on the measuring rod with its work surface location parallel to axis of the cone hole. The indicator is secured on the basing element, and its measuring rod is located above the basing element at right angle to axis of the cone hole, and is located with possibility of interaction between the clamp work surface and measured planes.
EFFECT: increased accuracy of measurements and simplified design.
