Conductivity: Solutions and spare parts

Components in contact with the measured medium always wear out to a greater or lesser extent. Long-term accurate and reliable measurement therefore requires maintenance. Depending on the type of sensors used, this mainly involves regular calibrations, replacement of worn parts, or entire sensors (where applicable).

You can easily handle a number of these common tasks yourself, saving time and costs. You can find the relevant procedures in the user's manual of the individual products, or we can also advise you over the phone. Below you will find the necessary materials.

Conductivity calibration solutions


Solutions of the SS ES 11 series are used for calibration of conductivity sensors. They are supplied in 100 ml, 500 ml or 1000 ml bottles.
