Available Parameters
The Aqua TROLL Instrument can also calculate and record
derived parameters as listed below.
For more information on measurement methodology, including
the equations used to derive the calculated parameters, see the
technical note “Aqua TROLL 200 Measurement Methodology” on
the In-Situ software/resource CD, or in the Downloads section of
the In-Situ web site at www.In-Situ.com.
Actual Conductivity
Units: micro siemens per centimeter (µS/cm), default
milli siemens per centimeter (mS/cm)
Specific Conductivity
A means of expressing what the actual conductivity of a solution
would be at a standard reference temperature (25° C). Calculated
from actual conductivity and temperature. The factory default
coefficients calculate specific conductivity per Standard Methods
2510B.
Units: micro siemens per centimeter (µS/cm), default
milli siemens per centimeter (mS/cm)
Salinity
Calculated from actual conductivity and temperature. Units:
Practical Salinity Units (PSU)
Total Dissolved Solids (TDS)
Calculated from specific conductivity using a conversion factor
(Default: 0.65).
The TDS conversion factor may be edited in Win-Situ as follows:
