Bilateral comparison: Calibration of conductivity probe in low conductivity range (20 µS/cm and 100 µS/cm)

Project Description

A bilateral comparison is proposed between LNE and PTB aiming to demonstrate the equivalence of cell constant calibration for a commercial conductivity sensor. The comparison will be organised as Round Robin test type. Measurements will be done at 25°C and at 2 nominal conductivities of 20 µS/cm and 100 µS/cm. The sensor will be provided by LNE.

The bilateral comparison represents a subsequent comparison of the EURAMET Project 1462 "Electrolytic conductivity at pure water level" (CCQM QM-S12). Contrary to EURAMET 1462, this exercise will enable LNE to use the setup typically used for its customers.
