Hanna Marine 981520 Monitor 
Marine Monitor pH, Marine Salinity and Temperature
Testing and monitoring salinity in saltwater
aquariums is an ongoing task.
The HI981520 is an easy to use vertical mount unit that continuously monitors and displays conductivity and pH.
The system can be calibrated at one or two points for pH and at one point for conductivity.
Seawater salinity is expressed in either parts per thousand (ppt), Practical Salinity Units (PSU), or Specific Gravity (S.G.). A high/low alarm can be configured for each parameter and the results are displayed on a large, easy to read LCD. The attached two-electrode conductivity probe
features a built-in temperature sensor for rapid, high-accuracy temperature readings.
The Hanna HI1286 pH double junction, gel-filled pH electrode features a PEI resin body that is easy to clean and resistant to many aggressive chemicals.
Additionally, the double junction design is less susceptible to clogging for fast and stable readings.
• Waterproof
• Automatic temperature compensation (ATC)
• Dual pin graphite EC probe
 
Backlit LCD
Easy to read backlit LCD display with the option to change LCD color from the setup menu
 
Automatic Calibration
A one or two-point pH calibration can be performed using one of the two standard buffer solutions: 7.01 or 10.01pH.  A one-point conductivity calibration can be performed using
35.00 ppt salinity standard solution. CAL Tags display in measurement mode after a calibration has been performed for visual reminder.
 
Automatic Temperature Compensation
All readings are compensated for variations in temperature and can be displayed with temperature values in °C or °F.  Choose °C or °F measurement through the setup menu.
 
Alarm Setup
High/Low alarms can be set for each supported parameter (or can be
disabled) quickly through the setup menu.
 
Alarm State
Alarms are generated when measured value exceeds or
drops below configured parameter High/Low Value.
 
Optional Acoustic Alarm
An acoustic signal can be generated each time an alarm is
triggered and can be silenced at the touch of a button. Enable
or disable this feature easily through the setup menu.
 
Choice of Units
Seawater salinity units can be chosen through the setup menu.
 
ppt
Measurements expressed in ppt are based on the
Natural Seawater Scale that extends from 0.00 to
80.00 g/L and covers 10 to 31 °C temperature range.
It determines the salinity based upon a conductivity
ratio of sample to standard seawater at 15 °C and an
approximate salinity value of 35 in seawater.
 
PSU
The practical salinity of seawater relates the ratio of electrical
conductivity of a normal seawater sample at 15 °C and 1
atmosphere to a potassium chloride solution (KCl) with a
mass of 32.4356 g/Kg water at the same temperature and
pressure. Under these conditions the ratio is equal to 1 and
S=35. The practical salinity scale may be applied to values 0
through 42.00 psu at temperatures between 0 to 35 °C.
 
Specific Gravity (S.G.)
Specific Gravity, or relative density, is expressed as
the ratio of the density of seawater, at a specific
temperature, relative to the density of the same
volume of pure water at a specific temperature.
The probes are secured with suction cups to the
back of an aquarium (tank) and are suited for
continuous measurement of conductivity and
associated parameters required in applications such
as seawater, saltwater aquariums, or aquaculture.
