The physicochemical value reproduced by the standard is specific electrolytic conductivity  ĸ. It is expressed in the SI units: S/m. The values of certified specific electrolytic conductivity are traceable to the DFM's (Danish Fundamental Metrology) and GUM's (Central Office of Measures in Poland) standards. Conductometric standards are distributed in 100 cm3, 250 cm3 and  500 cm3 packages, and are designed for the determination of the conductivity cell constant for the measurement  of the electrolytic conductivity.

We produce reference materials with non-standard values (other than in the table above) falling within the range (0.008 ÷ 12.0) S/m on special order.

The value reproduced by the conductometric patterns has been referenced to SI units (S, m). The RM conductometric certificate is issued as a reference material certificate confirming its metrological properties, including PCA accreditation symbols, together with the reference to the PCA status as a signatory to the multilateral agreements of EA MLA and ILAC MRA regarding mutual recognition.

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.
