Aquation Ethernet PAM Fluorometer Sensor


  • Ethernet enables operation via internet – i.e. control fluorometer from a different room or different continent,
  • Fully waterproof sensor for use in the greenhouse or field,
  • Low power consumption,
  • Access to full suite of command and programming via AquationDirect,

The Aquation Ethernet PAM Fluorometer Sensor is designed for use where an ethernet connection to the controlling PC is an advantage.  The ethernet link enables the Fluorometer Sensor to be accessed from your PC, while the sensor may be in another room in the building or kilometers away.  This can be particularly useful when conducting measurements remotely.

Applications can be as simple as operating the Fluorescence Sensor in a culture facility and being able to monitor the sensor from the convenience of your office, or at home.  The Aquation Ethernet PAM Fluorometer Sensor is functionally similar to other Aquation Classic fluorometers.

Application example: Coral assessment using an ROV

The Aquation Ethernet PAM Fluorometer Sensor was originally devised for use with a submersible Remotely Operated Vehicle (ROV), where the signal to and from the sensor installed on the ROV platform was conducted up the umbilical to a PC adjacent to the operator controls.  In this way the operator positioned the sensor up against a coral head, held the ROV in position and could then execute the PAM-fluorescence measurements as required.  Effective quantum yield measurements and Rapid Light Curves are possible with this approach.  Geooceans Pty Ltd provided essential support for this project.  Values of effective quantum yield of two separate coral heads were 0.39± 0.03 and 0.38± 0.08 (SD, n=6,8).
