ST-500 Walchem Sensor, Pyxis, inline PTSA

Pyxis inline fluorometers measure a wide variety of products and can handle many applications. In addition to measuring fluorescence, the ST-5xx series probes have extra photoelectric components that monitor the color and turbidity of the sample water. This extra feature allows automatic color and turbidity compensation to eliminate interferences common in real-world samples.

They offer 4-20 mA and RS-485 Modbus output signals, and are Bluetooth enabled for wireless cleanliness diagnostics and calibration when used with Pyxis Bluetooth Adapters and the uPyxis app. The sensors come in either CPVC or Stainless Steel models, or both.

• High resistance to color and turbidity interference from sample water
• Digital communication via Bluetooth to smartphone app for diagnosis and troubleshooting
• Highly stable and extremely reliable even in harsh application
