1. Press .
2. Press repeatedly until “tc On” is displayed
(see Figures 10 and 11).
3. Press ; the display will change to “tc OFF”.
4. Press ; all conductivity and TDS measurements are now
uncompensated.
Repeat steps 1-4 to reverse selection back to “tc On”.
XII. SALINITy UNITS (TPH1 & TP1)
“Salinity” Units may be selected in either COND or TDS mode, and in
ANY solution KCl, NaCl & 442. TDS 442 shown below, (ref. Solution
Selection, pg. 9).
Salinity (S) - A parameter used in oceanography to describe the
concentration of dissolved salts in seawater. It is defined in terms of
electrical conductivity relative to a standard solution of KCl.
When expressed in units of parts per thousand, the salinity may be
roughly equated to the concentration of dissolved material in grams per
kilogram (grams/liter) of seawater (NaCl). HC&P 85th edition 2-55
Since most applications do not use seawater, which is predominately
Sodium Chloride (NaCl), we highly recommend the solution of choice be
442™. 442 more closely matches the fresh natural water used in most
applications (ref. Conductivity/TDS Standard Solutions, pg. 24).
