Pyxis ST-500 Inline Fluorometer

Overview

The Pyxis ST-500 inline fluorometer probe is designed to measure the concentration of fluorescence tracer PTSA in cooling water. Its state-of-the-art design utilizes a unique optical design of a short fluidic channel and an advanced compensation algorithm. Calibration is quick and simple at any concentration from 40 to 200 ppb without the need to remove the probe from the tee.

It also provides additional information on working conditions such as LED performance, temperature, turbidity, and color information via MODBUS registers. The ST-500 can also handle high turbidity and high color water samples. Testing has shown that it can survive in tough water conditions with turbidity readings of 180 NTU.
