Underwater Solutions for a Wide Variety of

Deep Sea and Shallow Water Applications

The new, compact, and easy-to-operate AquapHOx underwater sensor platforms are flexible solutions for many applications. Besides stand-alone loggers with internal data storage for long term deployment, our transmitters offer fast sampling and easy integration into existing set-ups utilizing the integrated analog outputs.

​

The loggers and transmitters are available with a titanium housing for deep-sea applications to depths of 4000m. These devices are highly flexible when choosing your analyte and sensor format as optical oxygen, pH, and temperature sensors can be connected. 

​

For applications in shallow water, loggers and transmitters with a POM housing are available and can be deployed to depths of 200m. These devices are dedicated to one analyte but with the same flexibility concerning sensor format (i.e., caps or fiber-based sensor).

​

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

Ocean Habitats

Open Ocean

Deep Sea

Aquaculture

Coastal Habitats (i.e., coral reefs)
