What is the function of an Analyzer in a process?

• A. A device that monitors pH in water.
• B. Provides analysis of a sample from a process.
• C. A gauge for measuring viscosity.
• D. A tool for calibrating instrumentation.

Answer: (B)

An Analyzer in a process is meant to examine a sample taken from the process and determine its chemical makeup or concentration. It goes beyond measuring a single physical property by performing an analysis that reveals what components are present and in what amounts. The result provides information that the control system or operators use to adjust the process, ensure product quality, and safeguard operations. This distinguishes it from a device that simply monitors a property like pH, a gauge that measures viscosity, or a tool whose job is to calibrate instruments.
