System Description
The Orion 7070iX Total Residual Oxidant Analyzer can be
used on either the discharge side or the generation side of a
Water Treatment System for monitoring the TRO
concentration in the sample stream. The location of the
analyzer is a critical factor in ensuring fast response time and
care should be taken to install the analyzer as close as
possible to the source of the sample.
Analyzer Connections
The water connections to the analyzer include the following:
•
Sample water input – Flow from source to analyzer.
•
Fast-loop sample output – Sample water return.
•
