Technical background
The philosophy behind the NeuLog's plug and play
technology is based on each sensor's ability to store its
own data due to an internal flash memory chip and
micro-controller in each plastic NeuLog body. This
technology allows the sensor to collect and then store
the digital data in the correct scientific units (for
o
o
example:
C,
F, Lux, %, ppm).
The sensor is pre-calibrated at the factory. The built-in
software in the logger can be upgraded for free at any
time using the provided firmware update.
On the salinity probe, there are two electrodes of known
surface area with a known distance between them; this
allows for the sensor to determine the salinity of
solutions.
An electrical potential difference is applied to the
electrodes located on the salinity probe to generate a
current through the solution. If ions are present, the
current flows between the electrodes. Current flows
through solutions via ion transport therefore; the higher
number of ions present in a solution the easier an
electrical current can flow so a higher salinity value is
measured.
The electrodes alternate polarities to prevent a total ion
migration to either pole which could cause polarization
and electrolysis.
