Conductivity meters and cells should be calibrated to a standard solution before you use them. When selecting a standard, choose one that has the approximate conductivity of the solution to be measured.
A polarized or fouled electrode must be cleaned to renew the active surface of the cell.
- In most situations, the Electrode Cleaning Solution is an effective cleanser.
- Acetone easily cleans most organic matter and Chlorine solutions will remove algae, bacteria or moulds.
- To prevent cell damage, abrasives or sharp objects should not be used to clean an electrode.
- A cotton bud works well for cleaning, but care must be taken not to widen the distance of the cell.
