PyroScience stands for intriguing optical sensor technology: simple, compact & flexible sensor systems with expert customer support. With the new AquapHOx technology, we also offer a unique all-in-one flexible underwater solution to monitor the health of our oceans.

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.

This all-in-one premium deep sea transmitter is also available as deep sea long-time logger, and as shallow-water single analyte transmitter for pH and O2. 

Supported analytes. This meter features ONE optical channel compatible to a broad range of optical oxygen, pH, and temperature 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 Pt100 sensor head.

Titanium Housing. This device can be deployed to a depth of 4000m.

Digital Interface. A standard RS485 interface provides robust communication even at cable lengths up to several 100m. A USB 2.0 adapter cable is included for "plug and play" configuration / operation with Windows PCs.

Digital Protocol. Modbus RTU or PyroScience protocol (switchable)

Analog output. This device has integrated analog outputs (2x 0-5V, 2x 4-20mA (16 bit each)).

Broadcast Mode. A broadcast mode can be configured, where the device triggers itself periodic measurements with up to 40 Hz sample rate. The measurement results are given in real time at the analog outputs. No digital communication is needed in this mode.

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.
