Underwater Sensor Solutions

The simple, flexible and compact AquapHOx underwater sensor systems include stand-alone loggers with internal data storage for long-term deployment and transmitters which offer fast sampling and easy integration into existing set-ups with analog outputs.

Both loggers (APHOX-LX, APHOX-L-O2, and APHOX-L-pH) and transmitters (APHOX-TX, APHOX-T-O2, and APHOX-T-pH) are available in titanium housing for deep-sea deployments (down to 4000 m) and in POM housing for shallow water monitoring (down to 100 m). For oceanic total scale pH and ultra-fast/ultra-trace oxygen measurements at depths up to 6000 m, PyroScience also offers the APHOX-LX6 logger with autonomous in situ data collection and the APHOX-TX6 real-time transmitter for in situ profiling and flux measurements.

All AquapHOx devices are ideally suited for measurements in a variety of marine monitoring applications, including:

  • Ocean and Coastal Habitats
  • Deep Sea Research
  • Open Ocean Research
  • Water Column Profiling
  • Sediment Profiling
  • Oxygen Minimum Zones
  • Aquaculture
  • In-Situ Incubations, etc.
