Pyxis ST-500 Inline PTSA Fluorometer

If your water treatment chemical supplier can provide inhibitor with PTSA fluorescent dye in the formulation, the ST-500 makes it easy for our W600 or W900 controller to measure and control the concentration!

The Pyxis ST-500 inline fluorometer measures traced chemical residual every 4 seconds with 1% accuracy. Turbidity and color in most cooling tower applications interfere with traditional fluorometer measurements, and lead to significant dosing errors. With the ST-500’s proprietary optical design and sophisticated compensation algorithm, even in water containing up to 150 NTU turbidity and 4 ppm iron, errors can be reduced or eliminated.

Key Features

  • High resistance to color and turbidity interference from sample water
  • Digital communication via Bluetooth to smartphone app for diagnosis and troubleshooting
  • Highly stable and extremely reliable even in harsh applications
 

 

Pyxis SP-350 and SP-380 Handheld Fluorometers

The Pyxis SP-350 fluorometers measure the concentration of PTSA in a sample and the SP-380 measures both PTSA and Fluorescein. They have a built-in sample cell for ease of use.

Major features of these fluorometers include:

  • Extra color and turbidity parameters measured are used for automatic compensation to eliminate interference.
  • No sample cuvette is needed and variations associated with the cuvette is eliminated
  • Operates using AA batteries for >10,000 measurements per set
  • Single-point (100 ppb) calibration
  • 5 second warm up
  • Low maintenance field fluorometer
