To meet your needs, MANUMESURE proposes a range of calibration solutions with pH values of 4.005 ± 0.008 ; 6.865 ± 0.013 and 9.180 ± 0.050 traceable to the international reference standards.
Our pH-certified reference materials are produced in compliance with the NIST/IUPAC recommendations and the DIN 19266 standard.
The property value is directly traceable to the primary pH reference standards produced by the LNE French national metrology and test laboratory.
Our accreditation as a producer of reference materials ensures that you use the only pH buffer solutions with a specified storage life and uncertainty, backed by traceability to the S.I system, as recognized by COFRAC.
AN OFFERING TO MATCH YOUR NEEDS
Our goal is to meet your needs in terms of metrological quality and practical use. MANUMESURE has developed functional packaging and markets its reference materials in single-dose 25 ml flasks.
