For use with any standard pH or ORP sensor.
Measurement choices are pH, ORP, Redox, ammonia,
fluoride or custom ISE. The automatic buffer recognition
feature uses stored buffer values and their temperature
curves for the most common buffer standards available
worldwide. The analyzer will recognize the value of the
buffer being measured and perform a self stabilization
check on the sensor before completing the calibration.
Manual or automatic temperature compensation is
menu selectable. Change in pH due to process temper-
ature can be compensated using a programmable tem-
perature coefficient. For more information concerning
the use and operation of the pH or ORP sensors, refer
to the product data sheets.
Model 1056 can also derive an inferred pH value called
pHCalc (calculated pH). pHCalc can be derived and
displayed when two contacting conductivity sensors are
used. (Model 1056-0X-20-30-AN)
