Features

  • Tolerates repeated steam sterilization
  • Sensor response practically independent of flow
  • Fast response time
  • Dissolved oxygen (DO) sensor uses a 4-pin connection plug for quick disconnection from the cable (sold separately)
  • DO sensor can be used with the insertion mounting assembly or similar assemblies typically used with large scale batch processes that perform SIP cleaning
  • For smaller batch processes, the DO sensor can be threaded directly into the top plate and autoclaved if necessary
