ST-500 Inline PTSA Sensor

The Industry’s Most Reliable PTSA Sensor

The ST-500 inline fluorometer is a very popular model for real-time monitoring of inhibitor dose with its extreme accuracy and proven robustness in the application of fluorescence traced cooling programs. It is mostly used for feedback control to maintain the dosed concentration within a narrow band around the set point regardless of changes in cycle or heat load dynamics. Now the ST-500 series expand the target of measurement to a broad range of analytes, including fluorescein and naphthenic disulfonic ac
