FermSense Amperometric Dissolved Oxygen Sensor

DynamicPE FermSense DO is a sterilizable amperometric dissolved oxygen sensor featuring an expandable inner silicone bladder that holds the electrolyte within a 316L stainless steel cage. During SIP processes or autoclaving, the internal bladder expands first, taking the pressure off the sensitive measurement area — allowing maximum electrolyte presence with minimum risk of sensor damage. The membrane cartridge design is easy to use and durable enough to be reused multiple times if necessary.
