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.
