The ST-525 offers a proprietary design that utilizes LED light sources for the direct measurement of Fluorescein (Fluorescein Sodium Salt/Uranine, CAS# 508-47-8). This simple, smart sensor is perfect for a water treatment professional working in industrial boiler water and process treatment applications.
The ST-525 offers proprietary Pyxis Lab® algorithms to determine the concentrations of Fluorescein at levels as high as 60ppb while simultaneously measuring light loss through the optical channel to determine sensor cleanliness. The ST-525 offers a combination of 4-20mA as well as RS-485 Modbus output signals and is Bluetooth Enabled for wireless cleanliness diagnostics and calibration when used with MA-WB or PowerPACK Series Bluetooth Adapters and the uPyxis APP for Mobile or Desktop devices. The ST-525 Series is provided in CPVC with the standard Pyxis ST-001 inline 3⁄4” FNPT Tee assembly, 5-foot bulk-head cable with quick adapter and 1.5ft flying lead cable with quick adapter, enabling rapid wiring to any microprocessor controller, PLC or DCS system.
