Ultra-Trace Oxygen Sensor Replacement for OIM and OXYPro® UT / UTM
Oxygen Exchange Cap OEC-PSt9-NAU
A PSt9 sensor is integrated in a stainless steel cap, which can be used to replace a used sensor on an OIM (Oxygen Probe for In-line Measurement) or the OXYPro® UT / UTM. The ultra-trace sensor has a measurement range of 0 - 200 ppmv oxygen with a detection limit of 0.5 ppmv, so even smallest gaseous oxygen traces can be detected. The sensor is not autoclavable. It is ideally suited for monitoring oxygen sensitive applications or production processes in different industries.
- Measurements down to 0.5 ppmv oxygen (gaseous O2 only!)
- Fast response time
- Easy exchange due to barcode calibration
- Pressure resistant
