The ST-525SS is identical to the ST-525 but is offered in a 304L Stainless Steel body with 3/4 inch FNPT ports. Designed for high pressure applications, the ST-525SS measures for Fluorescein at a range of 0–60ppb. Like our other fluorometers, the ST-525SS internally compensates for color & turbidity, making it extremely reliable. This sensor is ideally suited for applications of monitoring boiler feed water or boiler blowdown. With a combination of 4–20mA & RS-485 Modbus outputs, you can connect the ST-525SS to any controller, PLC or DCS network.
To enable uPyxis features, connect the ST-525SS to our MA-WB Bluetooth® adapter. This sensor arrives with our ST-001 tee assembly, as well as all necessary cables for rapid installation.
