Laboratory calibration of sensors

ILAC accredited metrological services to guarantee the conformity and accuracy of your measuring instruments.

We provide accredited metrological services for
on your temperature probes

Measuring instruments need to be calibrated regularly to ensure compliance with standards. JRI has developed digital probes of the highest metrological quality, equipped with an internal memory for storing calibration coefficients and metrological data. Their interchangeability enables calibration in the laboratory by simple exchange, without immobilizing equipment or disrupting activity. This solution saves time and guarantees the accuracy of calibration operations.
