Handheld Devices
ST-730 Series are designed for monitoring the middle range turbidity in various applications. It is more robust and tolerant to fouling, particular matters, and air bubbles comparing to other online turbidity meters designed for relatively clean water applications.
It also offers desired resolution and accuracy comparing to high turbidity or commonly referred to as suspended solid meters (4000 to 9999 NTU).
ST-730 series turbidity probe measures two optical densities and two scattering intensities at two wavelengths. This helps measure a large turbidity range and yet maintain a fine resolution. This design also helps the probe run self-diagnoses.
Typical Applications
- Industrial water treatment process control, including raw water, cooling water, and wastewater.
- Surface water monitoring.
- Other chemical processes with middle range of turbidity.
Features
- Dual-wavelength: white LED and IR LED 90° scattering to achieve more reliable and accurate reading in a complex flow system.
- A small footprint compact design, similar to an industrial pH probe.
- Isolated 4-20mA output. No need for additional transmitter for easy connection to PLC and DCS.
- Isolated RS-485 output embedded for easy trouble shooting and calibration.

SP-350 Handheld Fluorometers
Pyxis SP-300 series fluorometers measure the concentration of a fluorescent substance in a liquid sample. These fluorometers have a built in sample cell and samples can be directly filled into the sample cell. SP-380, SP-395, and SP-400 are dual channel fluorometers. SP-380 measures PTSA and fluorescein. SP-395 measures halogenated azoles and naphthenic disulfonic acid (NDSA).SP-400 measures PTSA (1,3,6,8-pyrenetetras ulfonic acid) and conductivity with patent pending technology to combine cutting edge optical measurement with electrochemical measurement in the same sample cell.
Simple to operate

PTSA Determination with Immunity to Color and Turbidity
Insufficient attention has been paid to color and turbidity interference to the measurement accuracy of PTSA fluorescence. Pyxis proprietary technology provides robust measurement and achieves maximum rejection of interference by utilizing a state-of-the-art optical design and advanced compensation algorithm.
SP-350 PTSA reading compensates for sample turbidity up to 40 NTU and sample color equivalent to 5 ppm total iron. If sample turbidity is too high or the sample color is too intensive, SP-350 displays a warning. When this happens, filter water sample before testing.

ST-500 Series Inline Fluorometers
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.
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.
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.
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.
Typical Applications
- Traced cooling water treatment programs
- Traced boiler water treatment programs
Features
- Color and turbidity compensation for accurate readings, long-term stability, and less frequent calibration.
- Typical maintenance cycle in months, not weeks or days.
- 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.
- Isolated 4-20mA output: no need for additional transmitter for easy connection with PLC and DCS.
