Emerson Process Management's Rosemount Analytical 2054PH pH Analyzer is a legacy pH/ORP analyzer designed for inline monitoring of process streams. It connects with Rosemount 2054/1054-series pH sensors, using a high-impedance glass electrode signal that is conditioned by a preamplifier, either inside the sensor or in a remote preamp, before the signal reaches the analyzer. Emerson literature identifies the 2054PH as part of the Rosemount Analytical pH/ORP measurement family and notes its role in reading pH (and ORP when configured) in process environments.
