VIEW
The AMETEK Model 931S and Model 932S UV Analyzers use photometric
analysis to continuously monitor H
2
S levels in acid gas (and other) ap-
plications or other high dewpoint applications. The microprocessor
-based
Model 931S and Model 932S Analyzers minimize the complexity of these
tasks and simplify operation of the analyzer system.
