Quantrol Inline Flourometer, PTSA, 4-20mA / RS485 Modbus / Bluetooth - ST-500

ST-500 Inline Flourometer, PTSA, 4-20mA / RS485 Modbus / Bluetooth by Quantrol

ST-500 series probes are UV excited inline fluorometers for measuring the concentration of PTSA in cooling tower and RO water systems. Capable of low-level detection in ppb + 1ppb.

Key Features

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

Accurate Traced Chemical Monitoring:

The ST 500 inline fluorometer, state of the art technology was developed by Pyxis Lab, Inc. in the United States. It measures traced chemical residue every 4 seconds in the sample water with 2% accuracy. It allows an optimal narrow band control in the treatment chemical concentration for cost effectiveness and, more importantly, best treatment performance.

High Rejection to Turbidity and Color Interference:

Turbidity and color in most cooling tower applications interfere traditional fluorimeters and lead to significant dosing errors, even up to 50%. With the ST 500's proprietary optical design and sophisticated compensation algorithm, the ST 500 delivers great precision and accuracy for waters containing up to 150 NTU turbidity and 4 ppm iron. This breakthrough technology ensures ST 500 to outperform in the toughest cooling water applications while keeping maintenance demand at a minimum with our uPyxis diagnostics capabilities.
