Pyxis ST-5xx and ST-5xxSS Series
Inline Fluorometers

Pyxis inline fluorometers measure a wide variety of products and can handle many applications. In addition to measuring fluorescence, the ST-5xx series probes have extra photoelectric components that monitor the color and turbidity of the sample water. This extra feature allows automatic color and turbidity compensation to eliminate interferences common in real-world samples.

They offer 4-20 mA and RS-485 Modbus output signals, and are Bluetooth enabled for wireless cleanliness diagnostics and calibration when used with Pyxis Bluetooth Adapters and the uPyxis app. The sensors come in either CPVC or Stainless Steel models, or both.

Key Benefits:

  • 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 application

Pyxis ST-590 and ST-590SS Inline Fluorescent Polymer Fluorometer

The new ST-590 inline sensor is designed for the direct measurement of “Fluorescent Polymer” with a 410 nm excitation and 450 nm emission for use in industrial cooling water and process treatment applications.

Pyxis ST-500 and ST-500SS 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!

Pyxis ST-588 and ST-588SS Dual Inline PTSA and Fluorescent Polymer Fluorometer

The new ST-588 inline sensor is a proprietary design for the direct measurement of both PTSA (365 nm excitation / 410 nm emission) and “Fluorescent Polymer” (410 nm excitation / 450 nm emission) for use in industrial cooling water and process treatment applications.

Pyxis ST-525SS Inline Fluorescein Fluorometer

The Pyxis ST-525SS inline fluorometer probe measures the concentration of fluorescence tracer fluorescein in water up to 60 ppb. The stainless steel body of the ST-525SS probe makes it ideally suitable for applications of monitoring boiler feedwater or boiler blowdown after being cooled down to near ambient temperature.

Pyxis HM-500 Inline Oil in Water Fluorometer

The Pyxis HM-500 inline fluorometer probe measures the concentration of multiple oils in water, up to 1000 ppm, using LED-sourced UV fluorescence methodology.
