Measures for PTSA at an expanded range (0–300ppb), while simultaneously compensating for Color & Turbidity Interference, to provide a more accurate dosage reading
The ST-500W is a stainless steel inline PTSA Pyxis smart sensor. It is uniquely designed to be directly inserted into the WALCHEM® and alternative fluorometer tee assemblies. The ST-500W is designed for the WALCHEM® tee system. Most fluorometers have similar dimensions to this system. This allows drop-in installation into both designs of inline tee assemblies without the need for plumbing modifications.
