Sensor Cap for Air Bubble Reduction on OIM and OXYPro® TR / TRM
Oxygen Exchange Cap OEC30-PSt6-YAU
The Oxygen Exchange Cap OEC30 with integrated sensor type PSt6 is made of stainless steel and can be screwed to the top of an OIM or OXYPro® TR / TRM. Its beveled tip reduces air bubble formation during dissolved oxygen measurements. The OEC30-PSt6-YAU is available in different versions: safe for food application (CAF) or with a hydrophobic Teflon coating (PTFE) for measurements in aggressive environments. The PSt6 sensor has a maximum measurement range of 0 - 10 % oxygen, with a detection limit of 0.002 % O2 / 1 ppb. The OEC30-PSt6-YAU stands steam sterilization and cleaning in place.
- Maximum measurement range of 0 - 10 % O2
- Reduced air bubble formation
- Different versions: food applications, aggressive environments
- Easy exchange due to barcode calibration
- Stands SIP (recommended: + 121 °C, 30 min) & CIP (+ 80 °C, 2 % NaOH)
- Pressure resistant
