Conductivity applications for evaporation process control

Valmet conductivity meters are used at evaporation to control the purity of the condensate. Valmet offers retractable meters that are easy to maintain if boil-over occurs during the operation. Valmet conductivity meters have a lifetime of more than 10 years in evaporation control.
