Pyxis ST-500 Series Inline Fluorometer

Pyxis ST-500 Series Inline Fluorometer

The Pyxis ST-500 Series Inline Fluorometers are very popular models for real-time monitoring of inhibitor doses with their extreme accuracy and proven robustness in the application of fluorescence traced cooling programs. They are mostly used for feedback control to maintain the dosed concentration within a narrow band around the set point regardless of changes in cycle or heat load dynamics.

The ST-500 series expands the target of measurements to a broad range of analytes, including fluorescein and naphthenic disulfonic acid (NDSA) to bring your success of traced cooling programs to boiler and other applications.

Typical Applications

• Traced cooling water treatment programs
• Traced boiler water treatment programs

Features

• Color and turbidity compensation for accurate readings, long-term stability, and less frequent calibration.
• Typical maintenance cycle in months, not weeks or days.
• Works with WiFi and Bluetooth adapters for one-press calibration with the SP-910, 700, and 400 tools, and for firmware upgrades via your smart phone.
• Isolated 4-20mA output: no need for additional transmitter for easy connection with PLC and DCS.
