Multi-Channel O2 Meter for Use with Numerous Sensor Designs

OXY-4 ST (G2)

This multi-channel oxygen meter can be used with microsensors (230 μm fiber) in different designs, non-invasive sensors, dipping probes and flow-through cells (1 mm fiber). This makes it the ideal tool especially for benchtop applications. OXY-4 ST is compatible with sensor type PSt7 (detection limit 15 ppb, 0 - 100 % O2). It is operated with the PreSens Measurement Studio 2 software and offers separate temperature compensation for each channel. The software has numerous features, offers additional pressure and salinity compensation and allows controlling several single and multi-channel meters simultaneously. This oxygen meter is the solution for most precise micro-invasive or non-invasive oxygen measurements.

  • Measurement range of 0 - 100 % O2
  • For use with O2 microsensors, dipping probes, non-invasive spots & FTCs
  • Compensation of temperature, pressure & salinity for each individual channel
  • Controlled by PreSens Measurement Studio 2 software
