Overview
The NEW ST-588 inline sensor measures for both PTSA (365nm ex/ 410nm em) and Fluorescent “Tagged” Polymer (410nm ex / 450nm em) independently. Built for industrial cooling water and process treatment applications, the ST-588 measures for PTSA at a range of 0–200ppb, with capabilities of measuring as high as 500ppb, and Fluorescent Polymer at a range of 0–20ppm. Like our ST-500, the ST-588 offers internal algorithms that compensate for Color & Turbidity interference. Connect the ST-588 to your controller using dual 4–20mA or RS-485 Modbus output signals, one for each parameter! For mobile monitoring, configuration, diagnostics & more, connect the ST-588 to our MA-CR Bluetooth® adapter or one of our PowerPACK Series Auxiliary Bluetooth® adapters. The ST-588 sensor arrives with our standard ST-001 tee kit assembly, as well as all necessary wires for rapid install. If your system is too harsh for this CPVC sensor, we recommend taking a look at our 316L stainless steel variant – the ST-588SS!
