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:

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).

Suggestions for an accurate reading of the Conductivity (density)
Precise readings depend greatly on proper maintenance of the connected sensor. Beyond
its intrinsic qualities, how the sensor is cared for is particularly important. This will, in
fact, provide reliable readings. Below is a list of some simple suggestions for optimum
conductivity (density) readings in aquariums:
- Handle the probe with care.
- If the probe is stored out of the water, it must be thoroughly dried to prevent oxidation
of the electrodes.
Periodically clean the probe (every week) with tap water, subsequently drying it thoroughly
to eliminate any deposits.
- Periodically calibrate the instrument (approximately every month as indicated
to page 24) to correct any reading imperfections due to probe wear.
- Replace the probe after a period of approximately 15 months.
- Do not install the interface in direct contact with wet or damp parts.
- Never use calibration solutions that have been left open or have expired.
- After the bottled solution has been opened, it must be used in 6 months (if properly
closed after use). After this period it must be replaced.
- Position the probe in the tank or sump away from strong currents to prevent excessive
oxygenation inside the latter.
- Do not immerse the probe completely in water. The cable’s seam must always be ap-
proximately 2 cm above the water.
IMPORTANT
For reliable conductivity readings, use only AQUATRONICA electrodes and cali-
bration solutions.
The use of other brands of electrodes could cause incorrect readings of the
instrument.
NOTE: in case of malfunctions or any doubts about the use of this interface, please
contact AQUATRONICA’S free Technical Assistance.

DISPOSAL OF ELECTRIC AND ELECTRONIC PARTS
Pursuant to Article 13 of Legislative Decree No. 151 of 25 July 2005, “Imple-
mentation of Directives 2002/95/CE, 2002/96/CE and 2003/108/CE,
regarding the reduction in use of dangerous substances in electrical
and electronic equipment, as well as waste disposal”:
Products bearing the barred dustbin symbol must be disposed of
separately from other waste. The user must therefore dispose of
the product in question at suitable recycling centers for electronic
and electro-technical waste, or he/she must turn over the used
product to the retailer when buying a new equivalent product, on
a one-to-one basis.
Separate waste collection allows used equipment
to be recycled, treated and disposed of without negative con-
sequences for the environment and health, and it allows the
materials in the equipment to be recycled. Illegal dumping of the
product by the user entails the administrative sanctions stated in
Legislative Decree No. 22/1997 (Article 50 et seq of Legislative
Decree No. 22/1997).
Separate collection of used products and packaging allows mate-
rials to be recycled and used again. Reuse of recycled materials
helps prevent environmental pollution and reduces the demand
for raw materials.
Local regulations may provide for the separate collection of
household appliances at municipal waste sites or retailers when
a new product is purchased.
