The OIM-PSt6 oxygen probe for in-line measurement and process control provides accurate and reliable O2 measurements in the 0-5% / 0-2 mg/L range.

Advantages:

  • Autoclavable: SIP (+ 130 °C, 1.5 atm) and CIP (2% NaOH, + 80 °C)
  • Use after autoclaving without recalibration.
  • No need to clean and replace the membrane
  • No need to replenish electrolyte solutions
  • Pressure resistant
  • No polarization
  • Long shelf life

Description

Description

The PreSens OIM-PSt6 connects to an oxygen meter (oximeter) via optical fiber, has a standardized thread and length, and is compatible with most bioreactors and port adapters.

OIM-PSt6 in-line oxygen probe consists of a stainless steel fitting with an optical replaceable cap in which an oxygen sensor is integrated. The optical interchangeable cap is screwed onto the top of the metal fitting and can be easily replaced if required.

The PreSens sensor provides highly accurate oxygen measurements, very fast response times and is virtually maintenance-free as it contains no membranes or electrolytes. The sensor is fully autoclavable and sterilizable (CIP and SIP).

In-line oxygen sensors are ideal for use in harsh environments such as high pressure or oil / water mixtures. For example, to monitor and control production processes in biotechnology, pharmaceuticals, brewing and beverage industries.
