Welcome to Aquation
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 also designs and manufactures a range of Environmental Assessment and Water Quality Monitoring devices, including the Submersible Respirometer System, custom phytoplankton monitoring solutions, and automated water quality monitoring systems with telemetry for long-term unattended applications.
Macroalgae
Environmental studies including responses to irradiance, and stress induced by heavy metals, salinity, pesticides and ocean acidification
Unicellular algae
Determining cell density and photosynthetic efficiency in culturing facilities, potable water supplies, and both marine and freshwater water bodies; also used to estimate the presence of blue-green algae
Broadacre crops
Wheat and cotton in situ comparison of cultivar performance; examination of heat stress and water stress responses
Seagrasses
Environmental studies including responses to sedimentation, petrochemicals, dredging, reduced light availability
Coral
Research and environmental assessment addressing bleaching events, herbicide impacts and the effects of ocean acidification
Horticulture and Viticulture
Identification of optimal photosynthetic efficiency of commercial species exposed to water stress, elevated nutrients, unusual temperature regimes
Water Quality Monitoring
Solutions for the measurement, logging and telemetry of salinity, temperature, pH, dissolved oxygen, turbidity, chlorophyll a, CDOM. Aquation’s Water Quality Monitoring systems are variously mains-, battery- or solar-powered and in fixed or moving installations (e.g. ships of opportunity).
pH Sensing
Aquation recently developed a field-based pH monitor for ocean acidification studies; operating on battery power the device has low drift and requires infrequent calibration due to the stable optical measurement technique
Leaf Absorptance
Our Reflectance Absorptance Transmittance (or RAT) meter provides leaf absorptance properties using a simple method; values can be used in a range of different photosynthetic studies.
