The Endress+Hauser laboratory can now calibrate instruments for measuring temperature, pressure, liquid flow, pH and conductivity – regardless of their brands.
The Endress+Hauser laboratory has just obtained its Cofrac accreditation for the calibration of measurement chains and temperature transmitters using Pt100 probes. This accreditation complements that already obtained in the field of liquid flowmetry. The laboratory can now perform the calibration of instruments regardless of their brands, temperature, pressure, liquid flow, pH and conductivity measurement.
The accreditation issued by the French Accreditation Committee (Cofrac) guarantees that the Endress+Hauser laboratory, located in Huningue (Haut-Rhin), fully meets the requirements of the NF EN ISO/IEC 17025: 2017 standard as well as the Cofrac application rules for temperature calibration activities. This Cofrac accreditation is proof of the laboratory's technical competence in a clearly defined field of activity, the proper functioning of the laboratory and an adapted management system.
"This accreditation expresses the high level of performance of our temperature calibration capabilities. The skills of our technicians and the operating procedures implemented have been validated by this external and independent body. This is for our customers a guarantee of safety and quality", reports Christophe Heitzmann.
A Cofrac accreditation recognizes and attests to the competence and impartiality of the bodies audited at national or even international level. In France, Cofrac is the only national body designated and recognized by the State to issue accreditations in a specific field. Accreditation differs from certifications or approvals. It is comparable to an audit process, which acts as a second level of control. Accreditation is therefore at the top of the pyramid of trust.
Expertise and high-level technical resources
In order to offer the highest level of confidence to its customers in temperature measurement chain and transmitter calibration, the Endress+Hauser laboratory has developed the technical skills of metrologists in this field. The laboratory includes test equipment (oil, methanol and water baths, resistance bridges and Pt 25 reference probes) to perform calibrations over a temperature range from -65°C to 200°C with an uncertainty of up to ±0.030°C
Endress+Hauser has also set up an organization that makes the calibration process more fluid and avoids any bottlenecks. Results: "We guarantee that the calibration service will be carried out within a maximum of eight working days between the time we receive the instrument and the time we send it back to the customer. This period can be reduced to two days when the service has been scheduled by making a prior appointment," says Christophe Heitzmann.
Endress+Hauser's competence in metrology is also complemented by its robust expertise as a well-known manufacturer of measuring instruments. The company therefore does not simply issue a calibration certificate but when an instrument does not meet the expected measurement specifications, it is able to identify the causes and establish a diagnosis, in order to offer its customers appropriate corrective solutions such as adjustments or repairs in the event of abnormal drift observed.
