Other Instruments

SIET can also effect calibrations on instruments that are not included in the table above, thanks to the collaboration of partner laboratories of well-established experience and competence.

On Site Calibration

SIET, thanks to twenty years' experience in its own metrological laboratory in Piacenza, carries out calibrations of instrumentation also at customers' factories.

Instrumentation Management

Making use of a tried and tested procedure of Instrument Management entrusted to a team of professionals with expertise in metrology and Quality, SIET S.p.A. offers companies a personalised service of management of all their instruments, which includes:

  • check of the instrumentation used in every department on the basis of the measurements carried out;
  • classification and identification of the instruments and data base management;
  • definition of a detailed calibration programme and periodical checks depending on the characteristics of the measurements effected, the instruments used and their conditions of use;
  • regular checking of the instruments, carrying out of the calibration and issuing of Calibration Certificates or Reports;
  • definition of a regular maintenance programme and management of all possible problems;
  • supply of new instruments;
  • assistance in deciding on new measuring techniques.
