Measures conductivity in the range 0 to 600,000
µ
S/cm
(600mS/cm). Measurement choices are conductivity,
resistivity, total dissolved solids, salinity, and % concen-
tration. 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
2
SO
4
).
The conductivity concentration algorithms for these
solutions are fully 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 two contacting conductivity sensors are
used, Model 1056 can derive an inferred pH value
called pHCalc. pHCalc is calculated pH, not directly
measured pH.(Model 1056-0X-20-30-AN required)
Note: Selected 4-electrode, high-range contacting
conductivity sensors are compatible with Model 1056.
Input filter: time constant 1 - 999 sec, default 2 sec.
Response time: 3 seconds to 100% of final reading
Salinity: uses Practical Salinity Scale
Total Dissolved Solids: Calculated by multiplying
conductivity at 25 ºC by 0.65
