Fiber Optic ATR-Probes (Shaft-in-shaft design)

Main features

  • Fiber assembly is easy detachable.
  • No need to retract the whole probe out of the fermenter, just pull the fiber assembly out of the operational shaft and store it separately.
  • Sealing the operational shaft is possible for the sterilization, cleaning, deactivation or any other treatment.
