Perfusion Monitoring in Pipes
Oxygen Probe Integrated in Metal Flow-Through Connector FTM-PSt3
An oxygen exchange window is integrated in a metal flow-through connector. The FTM can be integrated in pipes with o.d. 6 mm or other diameters using the respective adapters. The oxygen probe is very robust and long-term stable. It can be cleaned by CIP (Cleaning in place 2 % NaOH, + 80 °C) and also stands steam sterilization (+ 130 °C, 1.5 atm).
- Online oxygen measurement in perfusion systems
- No consumption of oxygen
- Signal independent of flow velocity
- Autoclavable, SIP (+ 130 °C, 1.5 atm) & CIP (2 % NaOH, + 80 °C)
- Polarization-free
- Long-term stability
Applications
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.
