The Pyxis ST-588 inline fluorometer sensor simultaneously measures the concentration of PTSA and Fluo-rescent Polymer in water. It can be simply inserted to the compression fitting port of a custom-made tee. The standard ST-001 installation tee provided with each ST-588 sensor, has two ¾ inch female NPT ports and can be placed to an existing ¾ inch sample water line. Pyxis Lab also offers 2" and 3" Tee formats for larger flow installations. The 4ā20mA current output of the ST-588 sensor can be connected to any controller that accepts an isolated or non-isolated 4ā20mA input. The ST-588 sensor is a smart device. In addition to measuring PTSA and Fluorescent Polymer, the ST-588 sensor has extra photo-electric components that monitor the color and turbidity of the sample water. This extra feature allows automatic color and turbidity compensation to eliminate interference commonly associated with real-world waters. The Pyxis ST-588 sensor has a short fluidic channel and can be easily cleaned. The fluidic and optical arrangement of the ST-588 sensor is designed to overcome shortcomings associated with other fluorometers that have a distal sensor surface or a long, narrow fluidic cell. Traditional inline fluorometers are susceptible to color and turbidity interference and fouling and are difficult to properly clean.
