Versatile Multi-Channel Trace O2 Meter

OXY-4 ST trace (G3)

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.

  • 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 compensation
