CPV code 38810000 designates Industrial process control equipment in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
38810000 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 38800000 (Industrial process control equipment and remote-control equipment).
