Ph/Orp/Ise (Codes -22, -32, -42) - Emerson Rosemount 1057 Instruction Manual

Instruction Manual
LIQ-MAN-1057
1.4 pH/ORP/ISE (Codes -22, -32, and -42)
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 temperature can be compensated using a programmable
temperature coefficient. For more information concerning the use and operation of the pH or ORP
sensors, refer to the product data sheets.
Model 1057 can also derive an inferred pH value called pHCalc (calculated pH). pHCalc can be derived
and displayed when two contacting conductivity sensors are used as sensor 1 and sensor 2.
