Steel Probe for Monitoring Oxygen Traces in Processes
Oxygen Probe for In-Line Measurement OIM-PSt6
The OIM-PSt6 has a stainless steel fitting with standardized length and thread, so it is compatible with most bioreactors and port adapters. The optical trace oxygen sensor has a measurement range of 0 - 5 % oxygen and a detection limit of 1 ppb. It is integrated in an Optical Exchange Window, which is screwed to the top of the metal fitting and can be replaced if needed. The probe has excellent long-term stability and can be equipped with a customized fitting for e. g. sight glasses.
- Stands autoclaving, SIP (+ 130 °C, 1.5 atm) & CIP (2 % NaOH, + 80 °C)
- No membrane cleaning and replacement necessary
- No electrolyte solutions to replenish
- Pressure resistant
- Measurement in steel fermenters
- Trace oxygen measurements in brewing and beverage industries
Process Control in Biotech & Pharma
The OIMs, the oxygen probes for in-line measurement, are designed for harsh conditions like high pressure or oil/water mixtures. These systems give high accuracy and are almost maintenance-free as they do not contain any membranes and electrolytes. The sensors are fully autoclavable and sterilizable (CIP & SIP).
In-line Oxygen Measurement in Brewing and Beverage Industry
Even low concentrations of oxygen influence shelf-life and the taste of certain beverages. Due to the extraordinary low detection limit and outstanding accuracy of PreSens trace oxygen sensors, the quality of oxygen-sensitive products such as beer, wine and soft drinks is secured.
The optical sensors have – compared to standard electrodes – a very fast response time and they are very easy to maintain.
