Precision instruments for inspecting components of fuel equipment:
Model PR3M

The model PR3M instrument is intended to be used for measuring the opening’s diameter of the plunger’s bushings in sections of distributing pumps.

The diameter of the opening is measured along its entire length.

The instrument’s measuring head is set up on a special floating suspension, and owing to that the permissible deviations from alignment of the opening being checked and the component’s external location surface can reach 0.2 mm.

The instrument is furnished being set to check a specified diameter of an opening.
