Aquation Pty Ltd

Aquation Pty Ltd

Aquation Pty Ltd has designed and produced a range of chlorophyll fluorometers for the assessment of plant health. Our instruments measure the modulated fluorescence of chlorophyll, often referred to as the PAM technique. Our fluorescence products range from a simple and inexpensive netbook-operated Classic Fluorometer to our state-of-the-art fully submersible Shutter Fluorometer with multiple shuttered sensors for automated dark acclimation. While originally developed for underwater applications, Aquation fluorometers are equally effective in terrestrial environments. Applications of Aquation fluorometers include the assessment of photosynthetic efficiency of plants or algae within both commercial and research contexts.

Aquation Pty Ltd designs and manufactures innovative Chlorophyll Fluorometers for both on-land and underwater applications.  Chlorophyll fluorescence measurements give us insight into efficiency of light conversion (plants convert light to chemically stored forms of energy).  Hence, chlorophyll fluorescence measurements can tell us whether a plant is doing well, or poorly.  Aquation’s instruments are used in fields and forests, and underwater in seagrass meadows, coral reefs and macroalgal beds.

Aquation also designs and manufactures Environment Monitoring equipment including water quality monitoring systems and other land-based sensor network systems.

Chlorophyll Fluorometers

Photosynthetic performance can be easily measured with chlorophyll fluorescence and gas exchange techniques.  Aquation’s product range includes:

Applications of Aquation chlorophyll fluorometers include the assessment of photosynthetic efficiency of plants or algae within both commercial and research contexts.

  • Broadacre crops, e.g. wheat and cotton (in situ phenotyping and comparison of cultivar performance; examination of heat stress and water stress responses)
  • Horticulture and Viticulture (identification of optimal photosynthetic efficiency of commercial species)
  • Coral (e.g. bleaching events; effects of ocean acidification)
  • Seagrasses (environmental studies including responses to sedimentation and petrochemicals)
  • Macroalgae (environmental studies including responses to irradiance, and stress induced by heavy metals, salinity, ocean acidification)
  • Unicellular algae (determining cell density and photosynthetic efficiency in culturing facilities; also used to estimate presence of blue-green algae)

When used in the field, fluorescence sensors can be connected to Aquation’s self-contained data loggers including either the rugged Submersible Datalogger or the non-submersible Portable Datalogger.  These dataloggers can be configured to accept and log data from other proprietary sensors.  Self-powered and telemetered options are available.

Environment Monitoring

Environment monitoring including water quality monitoring uses a wide range of sensors, dataloggers, sondes and telemetry systems.  We provide you with as many options as possible so you get the best solution for your monitoring problem.  Solar power and cellular or satellite telemetry are standard features for use in regional and outback locations where power and communications are not readily available or convenient.  Aquation provides:

  • Water Quality Monitoring Systems: e.g. temperature, electrical conductivity (EC), dissolved oxygen (DO), pH, turbidity, Chl-a, phycocyanin/phycoerythrin. Most other sensors are available on request.  Depending on
  • Environment Monitoring Systems: e.g. specific land-based measurements may include temperature, relative humidity, insolation, soil moisture etc. We can provide our custom dataloggers or off-the-shelf dataloggers from our suppliers, and provide rugged weatherproof enclosures for long-term field deployments

Aquation also designs and manufactures unique devices and systems to address specific scientific problems.  Examples of projects include the design, development and manufacture of:

  • UV-transparent plastic incubation chambers for the incubation and assessment of tiles that have been deployed in Sydney Harbour for extended intervals.  Net metabolic rates of each individual tile are used to characterise the different locations examined.
  • Simple and robust submersible power supplies used to operate 12 V pumps underwater.1assess water quality and environmental health.
  • 100 L plastic respirometer chambers for in situ metabolism determination (both photosynthesis and respiration).
  • a FerryBox system now installed in one of the Sydney Harbour ferries, measuring dissolved oxygen, conductivity, temperature, turbidity, chl-a, phycoerythrin, fDOM and location (GPS).  Data is gathered semi-continuously and posted on the internet.
