Underwater Oxygen and pH Meters

PyroScience the new, compact and easy-to-operate AquapHOx platform is a flexible solution for many applications. Besides stand-alone loggers with internal data storage for long term deployment, there are also transmitters for fast sampling and easy integration into existing set-ups utilizing the integrated analogue outputs.
The logger and transmitter are available with a titanium housing for deep-sea applications up to 4000m. These devices are highly flexible concerning choice of analyte and sensor format as O2, pH and optical temperature sensors can be connected.
For applications in shallow water, loggers and transmitters with a POM housing are available which can be deployed up to 100m. These devices are dedicated to one analyte but with the same flexibility concerning sensor format (e.g. caps or fibre based sensor).

• Long-time O2 monitoring in ocean habitats
• Most sensitive trace O2 measurements in oxygen minimum zones or de-oxygenation events
• Measurements of ocean pH on the total scale with neglectable impact of salinity
• Contactless read-out of incubations chambers with integrated sensors and profiling over surface structures, in sediments and along gradients at high spatial resolution
• Simply exchange the sensor head, choose between different analytes (pH, O2 or T) and various sensor formats

The PyroScience AquapHOx long-term logger is ideally suited for monitoring critical parameters and their dynamics in different ocean habitats, including open ocean, the deep sea and coastal habitats like coral reefs or coastal waters. This all-in-one premium deep sea logger is also available as deep sea real-time data transmitter, and as shallow-water single analyte logger for O2 and pH.

Deep Sea Real-time Transmitter for Oxygen, pH or Temperature Sensors

The AquapHOx-TX is a real-time data transmitter for underwater operation down to 4000m water depth. It can be combined with a wide range of optical O2-, pH- or temperature sensors, offering unmatched flexibility for multiple applications with the same APHOX-TX device.
Simply exchange the sensor head, choose between different analytes (pH, O2 or T) and various sensor formats. Combined with our (ultra-)high speed sensors, the AquapHOx-Transmitters are ideal tools for fastest O2 water column profiling or eddy covariance measurements.

Oxygen Logger for Shallow Water

The AquapHOx-L-O2 is an oxygen long-term logger for stand-alone shallow-water operation down to 100m water depth. It offers a great flexibility regarding application, as it can be used with the entire underwater oxygen & temperature sensor portfolio with SUB-connector. Simply exchange the sensor head, choose between different O2 & T sensor formats. These include oxygen sensor caps for long-time monitoring, fiber-optic micro- & minisensors for O2 profiling in sediments & over surface structures (corals, coralline algae, seagrass, kelp, etc.) at high spatial resolution, and ultra-trace oxygen sensor caps for measurements in oxygen minimum zones or de-oxygenation events.
Simultaneous pH monitoring can be realized by parallel deployment of the AquapHOx-L-pH logger. For deployments >100m depth, please refer to our deep-sea multi-analyte logger AquapHOx-LX with titanium housing.

Shallow Water Transmitter for Optical Oxygen Sensors

The AquapHOx-T-O2 is a real-time transmitter for underwater operation down to 100m depth. It offers a great flexibility regarding application, as it can be used with the entire underwater oxygen sensor portfolio with SUB-connector.
Simply exchange the sensor head, choose between different O2 sensor formats. These include oxygen sensor cap for long-time monitoring, fiber-optic micro- & minisensors for oxygen sensing with high spatial resolution in e.g. coral reefs, and ultra-trace oxygen sensor caps for measurements in oxygen minimum zones or de-oxygenation events.
