A complete range of certified control standards with values ranging from 1,3 to 500000 µs to meet all the requirements for electrochemical analysis.

• Accurate to ±1%
• Traceable to NIST, meeting Ph. Eur. and USP requirements
• Tested using INAB accredited test methods to ISO 17025

Standard values (25 °C)

Used for determining cell constant - see recommendations of instrument manufacturer for the relevant cell design.

Premium values (25 °C)

These standards are for verifying that the measuring system (instrument, probe and operator) can accurately detect sample values in the area of interest (e.g., 20 μs/cm for low conductivity water used in the pharmaceutical sector, or 100000 μs/cm for environmental samples).
