The ST-500SS is identical to the ST-500 but is offered in a 304L Stainless Steel body with 3/4 inch FNPT ports. Designed for high pressure applications, the ST-500SS measures for PTSA at a range of 0–300ppb, utilizing LED UV light sources to determine a final value. Like the ST-500, the ST-500SS internally compensates for color & turbidity, making it extremely reliable. With a combination of 4–20mA & RS-485 Modbus outputs, you can connect the ST-500SS to any controller, PLC or DCS network.

To enable uPyxis features, connect the ST-500SS to our MA-WB Bluetooth® adapter. This sensor arrives with our ST-001 tee assembly, as well as all necessary cables for rapid installation.
