Precision instruments for inspecting components of fuel equipment:
Model RPA5

The model RPA5 Instrument is intended to be used for measuring the run-out of the cutting-off cone of the sprayer relatively to its central opening.

The inspection is carried out automatically after manually placing the component on the measuring stage. The result is shown on the visual panel of the instrument’s electronic unit.

The instrument is furnished with a setting-up that is meant to check a specified standard size sprayer’s body.

Main Technical Data:
