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-500W Inline PTSA Fluorometer
Pyxis has created a machined steel version of the ST-500 PTSA sensor that will fit into existing Walchem or Turner tees. These allow users of the Little Dipper 2 to switch to Pyxis without having to change the plumbing. They are supplied with a nut with a slightly larger hole to replace the Turner/Walchem nut, and with two o-rings – one to replace the Walchem tee o-ring, the other to replace the Turner tee o-ring.
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 ST-565 Inline Azole Fluorometer (HST)
The Pyxis ST-565 is a UV excited fluorescence probe for measuring the concentration of halogen stable triazole (HST) in cooling tower water in the range of 0 to 7.5 ppm.
Pyxis ST-540 Inline NDSA Fluorometer
The ST-540 Series are inline fluorometers designed for those desiring to conduct research and development of NDSA traced boiler or process water treatment programs. The ST-540 Series offer direct measurement of NDSA (Napthenic Disulfonic Acid CAS# 1655-29-4) utilizing LED light sources for use in boiler water and boiler feedwater measurement applications.
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.
