1 SWiFT Profilers - Introduction
The SWiFT profiler is available in two main forms –SVP and CTD. The SVP is fitted with sound
velocity, temperature and pressure sensors, the CTD is fitted with conductivity, temperature and
pressure sensors. Configuration and data download is via dedicated Valeport Ocean software - PC
or mobile device and can be integrated into 3rd party software if required.
SWiFT SVP
SWiFT CTD
Designed from the outset for a seamless workflow, SWiFT profilers provide survey-grade sensor
technology coupled with the convenience of Bluetooth connectivity and rechargeable batteries, an
integral GPS module, to geo-locate each profile, completes the package. Data can be easily and
quickly downloaded and reviewed wirelessly, via Bluetooth, using the either Valeport's Ocean for
PC or mobile for portable devices and instantly shared, in industry standard formats through email
and cloud services. Alternatively, use the provided USB data and charging cable to connect to
Valeport’s Ocean software package.
In addition to the directly measured sound speed, temperature and pressure observations of the
SVP version, Conductivity, Salinity and Density are calculated using Valeport’s proprietary
algorithm developed from extensive laboratory and field work;
For the Swift CTD, sound speed, salinity and density are calculated from the Conductivity,
temperature and pressure data.
With a minimum battery life of 5 days continuous use, in profiling mode and the convenience of
charging via USB, SWiFT is intended for coastal, harbour and inland hydrographic survey use and
offers the highest quality profiles in a compact, robust and portable package.

3 Sensors
3.1 Sound Velocity Measurement
Utilising Valeport's latest sound velocity sensor, each measurement is made using a single pulse
of sound travelling over a precisely known distance, so is independent of the inherent calculation
errors present in CTD calculated data. Valeport's unique digital signal processing technique
virtually eliminates signal noise, and gives almost instantaneous response; the digital
measurement is also entirely linear, giving predictable performance under all conditions.
Range:
1375 - 1900m/s
Resolution:
0.001m/s
Accuracy:
±0.020m/s
Response:
31.25 ms
3.2 Conductivity
The inductive conductivity sensor is optimised for water flow through to allow for minimal
disturbance to the water column while rapidly descending to the required depth.
Range:
0 - 80 mS/cm
Resolution:
0.001 mS/cm
Accuracy:
±0.01 mS/cm

The SWiFT SVP is fitted with PRT temperature sensor.
The SWiFT CTD is fitted with fast response Thermistor temperature sensor.
Type:
PRT | Thermistor
Range:
-5°C to +35°C
Accuracy:
±0.01°C
Resolution:

3.5 Optical Sensors
An optical sensor must be kept clean to operate correctly. Ensure that the SWiFT plus is powered
down before cleaning the sensor.
Use warm soapy water with a soft bristled brush to remove any light fouling.
For heavy fouling use a solvent (e.g Isopropyl alcohol) and a soft bristled brush.
Always rinse thoroughly after every use in clean, fresh water.
3.5.1 Fluorometers
3.5.1.1 Safety Statement
A Valeport Fluorometer is classified as Risk Group 1 under standard 62471. As the type is
classified as Risk Group 1 solely due to radiation in the visible band a hazard label is not required.
However,
•the LED used is in excess of the Exempt Group and that the viewer-related risk is
dependent upon how the user installs and operates the equipment.
•The exposure hazard value (EHV) for a Valeport Fluorometer in terms of distance is
320mm.
Never look directly into the optical aperture

3.5.1.7 Linear Observation Range
The linear range is the concentration range for which the fluorometer signal is directly proportional
to the concentration of the fluorophore. The linear range starts at the minimum detection limit
(MDL) and extends to the upper limit of the instrument (dependent on fluorophore properties,
optical filters, LED power, sample volume and optical path length).
The optical devices manufactured by Valeport have digital outputs only; at higher concentrations,
unlike analogue devices which generally flat-line at full-scale deflection (e.g. FSD 5V) the
fluorometer will continue to output a signal which increases with concentration (i.e. meaningful
data), though which is no longer guaranteed to be linear.
At very high fluorophore concentrations, signal quenching can occur, whereby the instrument
output does not increase linearly with fluorophore concentration (roll-off) and may decrease at
even higher levels.

To perform a quick linearity check, dilute a sample of dye 1:1 with RO water. If the reading
decreases by 50%, the sample is in the linear range. If the reading decreases by less than 50% or
even increases, the sample is above the linear range.
3.5.1.7.1 Quenching
Quenching refers to the reduction in fluorescence of a fluorophore. Several processes can result
in quenching:
Chloride is known to quench quinine sulphate and Fluorescein. It is, therefore, advisable to
prepare any fluorophore solutions with Reverse Osmosis (RO) or De-Ionised (DI) water.
Temperature quenching - as the temperature of the sample increases, the fluorescence decreases,
that is, fluorescence is sensitive to temperature. In order to improve accuracy, measure the
sample at different temperatures and derive corrections for changes in temperature.
Photo-bleaching (or fading) is the (permanent) degradation of a fluorophore molecule by light
resulting in lower signal levels. Photo-bleaching is dependent on exposure (intensity of light and
duration) and wavelength (UV is more damaging than longer wavelengths). Use of more robust
fluorophores is recommended to avoid photo-bleaching.
