1.3 Contacting Conductivity (Codes -20, -30 and -40)
Measures conductivity in the range 0 to 600,000 µS/cm (600mS/cm). Measurement choices are
conductivity, resistivity, total dissolved solids, salinity, and % concentration. The % concentration
selection includes the choice of five common solutions (0-12% NaOH, 0-15% HCl, 0-20% NaCl, and 0-25%
or 96-99.7% H
temperature compensated. Three temperature compensation options are available: manual slope
(X%/°C), high purity water (dilute sodium chloride), and cation conductivity (dilute hydrochloric acid).
Temperature compensation can be disabled, allowing the analyzer to display raw conductivity. For
more information concerning the use and operation of the contacting conductivity sensors, refer to
the product data sheets.
Note: When contacting conductivity sensors are used for sensor 1 and sensor 2, Model 1057 can
derive an inferred pH value called pHCalc. pHCalc is calculated pH, not directly measured pH.
Note: Selected 4-electrode, high-range contacting conductivity sensors are compatible with
Model 1056.
Input filter: time constant 1 - 999 seconds, default 2 seconds
Response time: 3 seconds to 100% of final reading
Salinity: Uses Practical Salinity Scale
Total Dissolved Solids: Calculated by
multiplying conductivity at 25 °C by 0.65
