The ST-565 Series inline sensor platform is uniquely designed for direct measurement of Halogen Stable Triazole (HST) or TolyTriazole (TTA) using LED UV light sources, tailored for industrial cooling water and process treatment applications. This series leverages Pyxis’s proprietary algorithms to accurately determine HST or TTA concentrations, while also assessing sample turbidity and color in low-contamination waters (under 40 NTU) for internal compensation. It features both 4-20mA and RS-485 Modbus output signals and includes Bluetooth capability for wireless diagnostics and calibration when paired with MA-WB or PowerPACK Series Bluetooth Adapters and the uPyxis APP for mobile or desktop devices. Constructed from CPVC, the ST-565 Series comes with a standard Pyxis ST-001 inline ¾” FNPT Tee assembly, a 5-foot bulkhead cable with quick adapter, and a 1.5-foot flying lead cable with quick adapter, facilitating seamless integration with any microprocessor controller, PLC, or DCS system.
