With the number 151/LC10.109, according to UNE- EN ISO/IEC 17025, to act as a calibration laboratory.
calibration laboratory
both permanent and “in situ”, in the area of Chemistry – Gas Concentration.

A permanent calibration laboratory is one that is designed and equipped to perform calibrations in a systematic way and in a controlled environment. This type of laboratory is mainly used for the calibration of measuring instruments and equipment. In the case of gas concentration, reference gases are used to calibrate the sensors of the gas detectors, providing greater accuracy and reliability in the results. In the case of flow measurement, calibrated reference equipment is used to determine the precision and accuracy of flow meters used in the industry.

On the other hand, “in situ” calibration refers to calibration performed at the place where the equipment is used. This type of calibration is especially useful for portable equipment used in fields and applications where it is not possible to perform calibration in a permanent laboratory. Calibration technicians travel to the site where the equipment is located and perform the calibration “in situ”, verifying the results obtained by the equipment and ensuring its correct operation.
