A conductivity cell designed for optimum flow-through, a fast-response thermistor temperature sensor and 0.01% pressure sensor together with a Fluorometer sensor, all synchronously sampling at up to 32Hz to deliver the highest quality profiles in a lightweight and robust package.
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 actual toxins is possible by means of laboratory analysis of water samples, but this can be costly and time-consuming.
However, Cyanobacteria contain 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 wavelength to ensure that the response is specific to Phycocyanin and not affected by false positive results from normal Chlorophyll a fluorescence.

The instrument is designed to operate autonomously. Setup and data extraction can be performed using a SubConn connector or via an optional Bluetooth connection with a PC. Multiple profiles can be recorded in the instrument by switching it on then off using the connector switch plug or magnetic switch key for Bluetooth operation. Bluetooth auto-pairing and discovery make connecting to the instrument simple and robust. The instrument can also operate in real time or cabled comms. Supplied with a traditional SubConn connector with a choice of communication protocols fitted as standard and selected by pin choice on the output connector:
Solid state non-volatile Flash memory
Supplied with DataLog X2 Windows based software, for instrument setup, control, data extraction and display.
Titanium Housing
Valeport’s Hyperion Phycocyanin Fluorometer sensor delivers high-performance measurements of Fluorescein, in a compact & robust package ideal as a standalone sensor, for ROV and AUV integration or used as part of a multi-sensor array and data logger.
Valeport’s SWiFTplus Multi-Parameter Profiler with a Phycocyanin sensor combines survey-grade sound speed, temperature and pressure sensor technology with Phycocyanin observations.
Perfect for both profiling or fixed mooring applications, the MIDAS CTD+ is a revolutionary Multiparameter CTD with a wide choice of standard sensors.
