Introduction - Hyperion Optical Sensor
Valeport’s range of Hyperion optical instruments delivers high performance optical measurements
for the following fluorometers parameters:
•
Chlorophyll a
•
Fluorescein (Uranine)
•
Phycocyanin
•
Rhodamine WT
•
Sulforhodamine B
and
•
Turbidity
in a compact & robust package ideal as a standalone sensor, for ROV and AUV integration or used
as part of a multi-sensor array with a data logger.
Offered as standard in a 6000m depth rated, Titanium housing the Hyperion mini type Optical
Instrument has a wide range (9 - 28V DC) isolated power supply, data output up to 16Hz and
RS232, RS 485 and Modbus RT communication protocols.
The Hyperion sensors can also be integrated into Valeport's SWiFT, rapidPro CTD and fastCTD
profilers and interfaced to MIDAS CTD+ (400 series) type instruments.
The Hyperion has an accurate single channel detector that can be used for many different
fluorophores. It is designed for integration into systems providing electrical power and delivers a
signal that has been correlated to a known concentration of fluorophore.

PCB Update
From November 2020 (serial numbers > 75100) a new PCB was introduced to the Hyperion
Fluorometer. The new MK2 PCB offers the same performance as the MK1 but no longer requires
the gain to be adjusted to achieve the full sensing range performance.
1.3
Calibration Update
From firmware version 903707A22 a new 2
nd
order calibration fit was introduced to improve
linearity at higher concentrations to counter some of the effects of quenching.
