Hanna Instruments HI98194 Instructions Manual page 27

Resistivity Unit (HI98194, HI98195 only)
The user can select resistivity from one of the following measurement
units: Ω·cm, kΩ·cm or MΩ·cm. Resistivity is calculated from the
conductivity measurement. The default unit is MΩ·cm.
Seawater Sigma Unit (HI98194, HI98195 only)
This parameter is used for seawater analysis. It is calculated from
the conductivity measurement and depends on water pressure,
temperature and salinity. The default value is σ
the reference temperature: σ
0 °C or 15 °C).
EC Resolution Unit (HI98194, HI98195 only)
The user can configure the conductivity resolution with one of the
following options:
Auto: the meter automatically chooses the range to optimize the
measurement. Readings can be in µS/cm or mS/cm.
Auto mS/cm: the meter automatically chooses the range to optimize the measurement, readings
will be in mS/cm only.
1μS/cm, 0.001 mS/cm, 0.01mS/cm, 0.1mS/cm or 1mS/cm: the meter will not autorange, the
measurement will be displayed with the selected resolution. The default value is Auto.
Absolute EC Resolution Unit (HI98194, HI98195 only)
Absolute conductivity displays the conductivity without temperature compensation. See EC resolution
for resolution details.
Note: A small letter "A" added to the μS/cm or mS/cm unit refers to an absolute
conductivity value (i.e. a conductivity reading with no temperature compensation).
TDS Resolution Unit (HI98194, HI98195 only)
The user can configure the TDS resolution with one of the following options:
Auto: the meter automatically chooses the range to optimize the measurement, readings can be in
ppt or ppm.
Auto ppt: the meter automatically chooses the range to optimize the measurement, readings will
be in ppt only.
1 ppm, 0.001 ppt, 0.01 ppt, 0.1 ppt or 1 ppt: the meter will display the measurement with
selected resolution. The default value is Auto.
