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. 

Supported analytes. This meter features ONE optical channel compatible to a broad range of optical oxygen and temperature sensors with SUB-connectors. The optical sensor of your choice must be purchased separately. Each optical sensor is automatically temperature compensated via an integrated fast NTC thermistor.

Stand-alone logging. Log your data (up to >1 year) without a connection to a PC with this stand-alone long-term logger. After the experiment, download the data with our included versatile Windows software for data processing. The integrated maintenance-free lithium battery is then recharged within <2 hours for the next deployment.

Huge data memory. This device comes with a built-in data memory of 4GB of industrial grade for ca. 40 million data points, offering virtually unlimited data memory even during long expeditions. 

Next generation PC software. The Pyro Workbench is our newest software solution and available as free download in the Downloads tab. Up to 10 PyroScience meters can be operated by the Pyro Workbench at once. It is used for configuring the device, calibrating the sensors, starting the logging, and finally for retrieving the logged data. The sensor readings are displayed numerically and graphically and can be logged in respective data files for further data processing. Additionally, the integrated Pyro Data Inspector features multiple data processing options like drift compensation or calculation of oxygen rates.

Innovative REDFLASH technology. The REDFLASH technology from PyroScience is based on the unique analyte-sensitive REDFLASH sensor materials. The REDFLASH sensor materials are excitable with red light and show an analyte-dependent luminescence in the near infrared (NIR). The REDFLASH technology impresses by its high precision, high reliability, low power consumption, low cross-sensitivity, and fast response times. The red light excitation significantly reduces interferences caused by autofluorescent samples. Further, the NIR detection technology significantly reduces interference with ambient light, known from the old blue-light techniques.

This project has received funding from the European Union's Horizon 2020 research and innovation programme SME-2 under grant agreement No 82964
