Model PH202G, PH202S, PH202SJ
2-Wire Type pH/ORP (Redox) Transmitter
GENERAL
Flexibility, low maintenance and low installation costs are
among the benefits of the EXA PH202 pH/ORP transmit-
ter. Designed to meet the exacting requirements of
measuring pH and ORP in the modern industrial environ-
ment, it contains many features to ensure peak precision
whatever the application.
This 2-wire (loop powered) transmitter is housed in a
robust IP65 field mountable case. HART
®
communication
is also available. The need for expensive cabling is
minimized. The famous EXA sensor diagnostics are
enhanced by an improved impedance check, and the
addition of a logbook feature. Calibration history is
available in the display, and is used to store important
configuration, calibration and diagnostic data. Prediction of
sensor failure is possible by reference to the logbook.
Microprocessor-aided calibration uses internal buffer
tables and stability checking to ensure maximum accuracy
with minimum effort. Process temperature compensation
enhances accuracy in applications where the influence of
temperature is seen in process pH changes. pH and ORP
or rH measurements can be made simultaneously when
an appropriate sensor combination is used.
