PyroScience stands for intriguing optical sensor technology: simple, compact & flexible sensor systems with expert customer support. With the newly extended AquapHOx series, we now also offer a flexible underwater solution for monitoring our oceans down to 6000 m into the deep Abyssal touching the Hadal Zone. Explore state-of-the-art surveying >80 % of the ocean area with our fiber-optical sensor solutions.  

Discover (Red)flashing pH and O2 sensing performance in the enduring dark depths of 4,000–6,000 m.

The AquapHOx-LX6 is a long-term logger for stand-alone underwater operation down to 6000 m water depth. It can be combined with a broad range of optical O2- or pH-sensors, offering unmatched flexibility for multiple applications with the same APHOX-LX6 device. These include e.g.

• long-time O2 monitoring down in the deep Abyssal Zone
• 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 choose the appropriate sensor head format for ocean pH or dissolved oxygen.

The deep abyssal logger is also available as deep abyssal realtime transmitter, as deep sea logger and transmitter down to 4000 m and as shallow-water (100 m) single analyte logger for O2 and pH.

Titanium Housing. This device can be deployed to a depth of 6000 m.

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.

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

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. 

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.
