Replacement Trace Oxygen Sensor for OIMs or OXYPro® TR / TRM
Oxygen Exchange Cap OEC-PSt6-YAU
The Oxygen Exchange Cap with integrated sensor type PSt6 is made of stainless steel. The sensor has a maximum measurement range of 0 - 10 % oxygen, with a detection limit of 0.002 % O2. The OEC-PSt6-YAU is available in different versions: YOP for bioprocess monitoring, safe for food applications (CAF), or with a hydrophobic Teflon coating (PTFE) for measurements in aggressive environments. It can be screwed to the top of an OIM (Oxygen Probe for In-line Measurements) or the OXYPro® TR / TRM. This way a used sensor can easily be exchanged as the cap can be calibrated with one fast barcode scan. OEC-PSt6-YAU stands cleaning in place & steam sterilization.
- Maximum measurement range of 0 - 10 % O2
- Different versions: food applications, aggressive environments
- Stands SIP (max. + 140 °C, 1.5 atm) & CIP (+ 80 °C, 2 % NaOH)
- Easy exchange due to barcode calibration
- Pressure resistant
Applications
Process Control in Biotech & Pharma
The OIMs, the oxygen probes for in-line measurement, are designed for harsh measurement conditions. 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.
