The physical-chemical value reproduced by the standard is the value of the oxidation-reducing potential (redox potential). Depending on the reference electrode and temperature, the values of the redox potential of the standards depending on the reference electrode and temperature are given in reference material certificate.

The standards are distributed in packages with a capacity of 100 cm3.

The standards are designed for calibration and checking of measurement systems used for redox potential measurements.

The CRM redox certificate is issued as a reference material certificate confirming its metrological properties including PCA accreditation symbols, that confirm compliance with the requirements of ISO 17034 for manufacturers of reference materials.

For redox reference materials, a reference material certificate for compliance with ISO 17025 can be issued, which shows metrological properties with PCA accreditation symbols based on the signatory status of multilateral EA-MLA and ILAC-MRA agreements on mutual recognition of calibration certificates.

CALIBRATION LABORATORY ACCREDITED by Polish Centre for Accreditation, a signatory to EA MLA and ILAC MRA that include recognition of calibration certificates. The laboratory meets the requirements of standard PN-EN ISO/IEC 17025.
