Hyperion Phycocyanin Sensor

Valeport Water’s Hyperion Phycocyanin sensor delivers high-performance measurements of Phycocyanin (freshwater Blue-Green algae) in a compact and robust package ideal as a standalone sensor (with external power and logger e.g. EnviroLog) for ROV and AUV integration or used as part of a multi-sensor array.

Offered as standard in a 6,000m depth rated, titanium housing the Hyperion Fluorometer has a wide range (9-28V DC) isolated power supply, data output up to 16Hz and RS232, RS485 with ASCII and Modbus RTU communication protocols.

Hyperion offers an industry-leading dynamic range with no adjustment of gain settings required. The detection range for the Phycocyanin Fluorometer is from 0 to 9,000 ppm.

Hyperion Fluorometers can be supplied in a ruggedised form that includes acetal protection rings, a shaped anti-snag connector cover and a kevlar weave protected cable for operation in borehole applications.

Cyanobacteria | Freshwater Blue-Green Algae

Cyanobacteria (or blue-green algae) are photosynthetic bacteria that occur naturally in surface waters. Under certain conditions of light, temperature and nutrient levels cyanobacteria can multiply rapidly, forming a bloom. Some Cyanobacteria produce toxins which pose health risks for humans and animals. The EU Bathing Waters Directive, therefore, requires monitoring for these blue-green algae blooms.

Testing for the actual toxins is possible by means of laboratory analysis of water samples, but this can be costly and time-consuming. However, cyanobacteria contain a fluorescent pigment called Phycocyanin, which can be detected in real-time using a Valeport Hyperion fluorometer. The Hyperion uses narrow bandpass filters on both excitation and emission wavelengths to ensure that the response is specific to Phycocyanin and not affected by false-positive results from normal Chlorophyll a fluorescence.
