The ST-500 Series inline sensor platform is a proprietary design for direct measurement of PTSA. It utilizes LED UV light sources for use in industrial cooling water and process treatment applications. The ST-500 Series offers unique algorithms to determine the concentrations of PTSA while measuring sample turbidity and color in highly contaminated waters.
The ST-500 Series offers a combination of 4–20mA as well as RS-485 Modbus output signals. Bluetooth enabled for wireless cleanliness diagnostics and calibration. When used with the MA-WB or PowerPACK Series Bluetooth Adapters and the uPyxis® mobile and desktop app. The ST-500 Series is provided in CPVC with the standard 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.
