What is PTSA testing?

In this method, a colorless fluorescent dye called PTSA is added to the cooling water inhibitor, serving as a treatment level tracer. PTSA levels can be accurately measured in about 30 seconds using a handheld or in-line fluorometer, requiring no harmful chemical reagents.

What is a PTSA probe?

tetrasodium salt (PTSA) Probe Calibration. Pyxis ST-500 and Turner Little Dipper2 PTSA probes are used to measure concentrations in parts. per billion (PPB) of fluorescence treatment chemicals in cooling tower systems. The PTSA probes output a 4-20mA signal that the MicroVision EX converts to PPB (parts per billion).
