Underwater logger for pH, oxygen or optical temperature sensors

PyroScience have expanded their product portfolio to include innovative underwater sensing solutions with their new AquapHOx technology.

The AquapHOx-LX is a multi-analyte long-term logger for standalone underwater operation down to 4000 metres depth. It can be combined with a wide range of optical O2, pH or temperature sensors, offering maximum flexibility regarding application. Simply exchange the sensor head, choose between different analytes (pH, O2 or T) and various sensor formats.

The AquapHOx long-term loggers are ideally suited for measurements in different ocean habitats, including open ocean, the deep sea and coastal habitats like coral reefs.

This meter features a single optical channel compatible to a broad range of optical O2, pH, and temperature sensors with underwater connectors. The optical sensor of choice must be purchased separately, so users only need buy the specific sensors that they need. Each optical sensor is automatically temperature compensated by the integrated fast Pt100 sensor head.

Operators can log data for up to 1 year without needing a connection to a PC with this stand-alone long-term logger. 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. After the experiment, download the data with PyroScience’s included versatile Windows software for data processing. The integrated maintenance-free lithium battery is then recharged within 2 hours for the next deployment.

The Pyro Workbench is PyroScience’s newest software solution and available as free download in the downloads tab on their website. Up to 10 PyroScience meters can be operated by the Pyro Workbench at once. This software can be used for setting up the meters and calibrating the sensors. The sensor readings are displayed numerically and graphically and can be logged in respective data files for further data processing.

PyroScience’s Redflash technology is based on their unique analyte-sensitive Redflash sensor materials. The Redflash sensor materials react with red light and display an analyte-dependent luminescence in the near infrared (NIR) range. The Redflash technology offers high precision, high reliability, low power consumption, low cross-sensitivity, and fast response times. The red light reaction significantly reduces interference caused by auto-fluorescent samples. Moreover, the NIR detection technology significantly reduces interference with ambient light, known from the old blue-light techniques.
