Calibration Laboratory

The periodical calibration of the process control instruments and the standards guarantees the reliability of measurements and therefore the quality of the finished products.

The calibration process, understood as the comparison between the values indicated by a measuring instrument and those indicated by a standard of higher level, allows several advantages:

  • Guarantees the traceability of measurements.
  • Reduces variations of the technical specifications of products.
  • Prevents defects and makes measurements compatible.
  • Standardizes procedures.

Our Calibration Laboratory PRYMELAB is accredited by CGCRE
(under the number CAL 193 – ISO/IEC 17025:2017) and belongs to the BRAZILIAN CALIBRATION NETWORK (RBC), follows the Quality Management System in accordance with ISO9001:2015.

We provide certification of our calibrators in the following scopes:

  • Range from 2 Pa up to 16000 psi (1100 bar)
    In gauge, absolute and vacuum modes with uncertainties up to 80 ppm (digital gauge), up to 100 ppm (analog gauge) and up to 150 ppm (pressure transducer).
