Overview

The Pyxis ST-500 Inline Fluorometer is an advanced smart sensing device used primarily in industrial water treatment applications such as cooling towers and reverse osmosis systems. It measures PTSA concentration using UV fluorescence technology, enabling precise control of chemical dosing in real time.

The sensor is engineered for harsh industrial environments and includes automatic compensation for water color and turbidity, reducing measurement interference and improving long-term stability. It supports Bluetooth connectivity for remote configuration, calibration, and diagnostics via mobile or desktop applications.

With its compact inline design, the ST-500 integrates easily into standard piping systems using a tee assembly. It is widely used for optimizing chemical feed programs, improving operational efficiency, and ensuring consistent water treatment performance.
