The popular ST-500 inline fluorometer is a robust and highly accurate tool for real-time monitoring of inhibitor dose. It is often used for feedback control to maintain dosed concentration within a narrow band around the set point, regardless of changes in cycle or heat load dynamics.<\/p>\n

Now the ST-500 series includes expanded measurement targets for a broad range of analytes, including fluorescein and naphthenic disulfonic acid (NDSA), and brings its proven record of reliability to your traced cooling programs for boiler and other applications.<\/p>\n

\"\"<\/div>\n

Thanks to its state-of-the-art fluorescence technology, the ST-500 Series handles a wide range of real-world sample water conditions. With its flow-through optical design and multiple wavelength color-turbidity compensation algorithm, the ST-500 probe maintains high performance for water samples with up to 100 NTU turbidity and\/or 5 ppm iron.<\/p>\n

The competitive probe comparison shown in the experiment below clearly demonstrates the superior performance of the ST-500 probe in the presence of iron color.<\/p>\n

Typical Applications<\/h3>\n
    \n
  • Traced cooling water treatment programs<\/li>\n
  • Traced boiler water treatment programs<\/li>\n<\/ul>\n

    Features<\/h3>\n
      \n
    • Color and turbidity compensation for accurate readings, long-term stability, and less frequent calibration.<\/li>\n
    • Typical maintenance cycle in months, not weeks or days.<\/li>\n
    • Works with WiFi and Bluetooth adapters for one-press calibration with the SP-910, 700, and 400 tools, and for firmware upgrades via your smart phone.<\/li>\n
    • Isolated 4-20mA output: no need for additional transmitter for easy connection with PLC and DCS.<\/li>\n<\/ul>\n
