The Memosens CPS97D is the specialist for measuring fibrous media or media with high suspended solids concentration (e.g. dispersions, precipitants, emulsions). The electrode shaft does not break and has a long service life; the open aperture enables reliable measurement under harsh conditions. In addition, the Memosens digital technology offers maximum process and data integrity with simple operation. The electrode is moisture- and corrosion-resistant, allows laboratory calibration and enables predictive maintenance.
