pH, pH-mV, ORP, DO % Saturation, Salinity
These parameters can only be enabled or disabled; measure unit and resolution
are fixed.
DO concentration
The user can select ppm or mg/L measure unit.
Conductivity and Actual Conductivity
The user can select among the following options:
Auto (autoranging for all µS/cm and mS/cm
ranges), 1 µS/cm, 0.001 mS/cm, 0.01 mS/cm,
0.1 mS/cm, 1 mS/cm, Auto mS (autoranging for
mS/cm ranges).
NoteNote
NoteNote
Note Actual conductivity is the conductivity value measured with no tempera-
ture compensation.
Resistivity
The user can select the measure unit among
Ω·cm, kΩ·cm and MΩ·cm.
TDS
The user can select among the following options:
Auto (autoranging for all ppm [mg/L] and ppt
[g/L] ranges), 1 ppm (mg/L), 0.001 ppt (g/L),
0.01 ppt (g/L), 0.1 ppt (g/L), 1 ppt (g/L), Auto ppt
(g/L) (autoranging for ppt [g/L] ranges).
NoteNote
NoteNote
Note For setting ppm or mg/L, see paragraph 3.2 “System Setup”.
Seawater specific gravity
This parameter is widely used for seawater analysis, it is similar to a density mea-
surement and gives indication about the salt content. It depends on water pres-
sure, temperature and salinity.
In the seawater specific gravity menu the user can select the reference tempera-
ture: σ
t
, σ
0
and σ
15
(i.e. current temperature, 0°C and 15°C).
Atmospheric pressure
The user can select among the following mea-
sure units: atm, kPA, mmHg, inHg, mbar, psi.
