Versatile Multi-Channel Trace O2 Meter

  • Measurement range max. 0 - 100 % O2 (PSt7) or 0 - 10 % O2 (PSt8)
  • For use with O2 microsensors, dipping probes, non-invasive spots & FTCs
  • Individual temperature compensation for each channel
  • Pressure & salinity compensation1

The OXY-4 ST trace can be used with O2 microsensor in different designs, non-invasive sensors, dipping probes or flow-through cells. This makes it suitable for precise oxygen measurements in various applications. This trace oxygen meter is compatible with sensors type PSt7 (detection limit 15 ppb, 0 - 100 % O2) and trace oxygen sensors type PSt8 (detection limit 3 ppb, 0 - 10 % O2). OXY-4 ST trace is operated with the PreSens Measurement Studio 2 software, which offers numerous functions for most precise trace oxygen measurements. this measurement device has separate temperature compensation for each channel and the software offers additional compensation of pressure and salinity. Several devices can be controlled simultaneously with the software, so measurement networks can be set up.

Applications

Food & Beverage: Oxygen Permeation Measurement in PET Bottles

Non-invasive oxygen sensors measure both in liquid and in gaseous (headspace) phases. They perform through transparent materials up to a thickness of 10 mm and even through slightly opaque packaging. The measurement is carried out by firmly holding the fiber optic probe against the side of a PET bottle where the sensor spot is positioned. Adjustable mountings and bespoke fixtures are available. This system allows even the parallel measurement of different bottles as the fiber can be moved from bottle to bottle.

Long-term Measurements in Soil

PreSens offers dipping probes for oxygen measurement that does not consume oxygen. Due to their small dimensions they do not disturb the flow and mass-transport and consequently display the in-situ oxygen concentration. As minisensors from PreSens are long-term stable they can be implanted in soil for many years! With this new method the process of soil aeration, which is very critical for plant productivity, can be investigated.
