Water density (or conductivity) is one of the parameters fundamental for the survival of
sh and invertebrates in an aquarium.
The amount of salt in the water can be established in various ways with different units of
measure. Electronically, however, electric conductivity can be measured once and through
a series of mathematical calculations the same quantity can be expressed with different
measurement units.
Aquatronica customers can therefore view the saltwater density in four different ways,
as they prefer.
So it is possible to choose which of the following values will be displayed:
Conductivity: Representing the content of mineral salts dissolved in water. It can be
measured electrically and is expressed in mS/cm (milliSiemens per centimeter) or µS/cm
(microSiemens per centimeter).
Salinity: Representing the amount of salts dissolved in a water sample. It can be expressed
in parts per thousand (ppt or PSU).
Density: Representing the ratio between the mass and volume of a liquid. Usually ex-
pressed for water in g/l (grams per liter).
Specic Gravity: Also called relative density, it is a dimensionless value representing the ra-
tio between the density of a liquid and the density of the same volume of water at 4°C.
A table on the back shows these values in their relative units of measure.
Aquatronica’s High-Range Conductivity Interface connects an Aquatronica high con-
ductivity probe to the “Aquarium Controller” system to measure and control the density
(conductivity) in aquariums.

After connection, the control unit will display a Plug-In
screen (Fig. 1), where a name can be assigned to the
connected sensor.
It may take several seconds for the control unit to
recognize the connected interface.
NOTE: The sensor’s name can be changed using
the control unit’s keypad.
If more than one of these sensors is connected, the user
may assign different names for each one to facilitate
menu navigation.
Displaying the read value
After the probe has been connected through the ap-
propriate interface, the values read by the probe will
be displayed on the main screen.
If several sensors were connected, their values can be
checked in order by pressing the and  keys.
Density Menu
Once the probe and interface are connected, the “Den-
sity” menu will appear in the “Main Menu”, where all
of its settings can be programmed. All sensor menus
have the same structure in order to make them more
intuitive and simple.
In this menu it is possible to change the name of the
connected sensor, calibrate it in order to obtain a more
accurate reading, enable an acoustic or visual alarm,
read the conductivity (density) of the previous day,
week or month (selected in the “Settings” menu) and
enable/disable the outputs based on the read value.
Change name
This option modies the name given to the sensor
(Fig. 4).
To use this option, proceed as follows:
Main screen Main Menu Density Change Name.
• Select the letter to insert using the  keys and move

Programs
This option is used to create programs based on the
Density value.
To set up a program, the following must be estab-
lished:
- A reference value, dened as the Density for the
tank, which the system will aim to maintain.
- A ∆Max value, dened as the tolerance that must
be observed with respect to values higher than the
reference value.
For example: If the reference is set to 1.0240 and the
∆ Max is 0.0010, the system will be enabled at values
higher than 1.0250 (see chart).
- A ∆Min value, dened as the tolerance that must
be observed with respect to values lower than the
reference value.
For example: If the reference is set to 1.024 and the
∆ Min is 0.0020, the system will be enabled at values
lower than 1.0220 (see chart).
To insert a program, proceed as follows:
Main screen Main Menu Density Programs.
• Select “Insert” using the  keys and press
“Enter” (Fig. 5).

Calibrate Sensor
This menu allows you to calibrate the density probe
through the interface. By using the keys , you may
choose whether to perform a new calibration by selec-
ting “New”, or to delete a previous one and reset the
interface to the default settings by selecting “Reset”
(Fig. 16). A calibration should be performed when the
interface is rst connected to the system.
Note: Before performing the calibration, the probe
must be rinsed using tap water, dried carefully and
inserted in the Aquatronica conductivity (density)
solution.
In order to correctly calibrate the sensor, proceed as
follows:
Main screen Main menu Density Calibrate Sensor
New.
1) Select the function “New” by using the keys 
then press “Enter” (Fig 15).
2) Using the keys  set the value of the standard
solution next to “Calib. Value” (Fig. 17).
3) Wait 10 minutes in order to allow the probe’s read
value to stabilize. The read value may stabilize on a
value that is slightly different than the reference.
NOTE: keep the probe as straight as possible inside
the solution container.
4) Once 10 minutes have elapsed, press “Enter”.
5) The controller will display the calibration result (Fig.
18); rinse the probe and insert in aquarium
Note: the calibration may be cancelled at any time
by pressing “Esc”. This will return the calibration
parameters to those of the last completed calibration.
