The EasyFerm Plus family of pH sensors is designed to withstand demanding applications in the pharmaceutical industry. The Phermlyte electrolyte and HP Coatramic diaphragm are specific features that when paired with the pre-pressurized reference design prevent clogging and chemical ingress from the process liquid. The Everef-F reference cartridge further ensures that the reference electrolyte remains free of silver and precipitation of proteins. The EasyFerm Plus is most commonly matched with its PHI membrane glass, due to its excellent chemical robustness and greatly reduced drift in applications where sterilization either in an autoclave or an SIP is performed frequently.
