Digitalization of a calibration laboratory: Batch calibration

The Metrology and Calibration Centre (CMC) at the National Institute of Aerospace Technology (INTA) has introduced an innovative tool designed to enhance the efficiency and effectiveness of calibration processes within its facilities. This cutting-edge software enables technicians to conduct multiple calibrations simultaneously, provided the requisite experimental setup is in place. Developed with a focus on streamlining the entire calibration workflow, from data acquisition to certificate issuance, the software ensures compliance with the ISO/IEC 17025 standard. Through rigorous testing, the CMC verified the software's performance using devices employed for monitoring ambient conditions (temperature and humidity) across various INTA test laboratories. Notably, these devices underwent batch calibration in groups of six, resulting in a sixfold reduction in experimentation time. Although the associated paperwork was reduced, the necessity to maintain traceability and issue individual calibration certificates for each device offsets the time savings.
