SP-350P Tagged Polymer Handheld
The Pyxis SP-350P is a uniquely designed handheld multimeter that measures Fluorescent Polymer. It is a cuvette-less device. Less than 5 mL water sample is needed to fill the sample cell for proper measurement.
The Pyxis SP-350P analyzer measures the concentration of Fluorescent Polymer of a water sample and includes the following features:
- Pre-calibrated for measuring Fluorescent Polymer in the range of 0 to 20 ppm. The Fluorescent Polymer measurement is automatically compensated for sample color and turbidity interference.
- Fluorescent Polymer can be calibrated with three standards (0, 10 and 20 ppm) through a user-friendly, menu-driven procedure.
- No sample cuvette is required and as such variations associated with the cuvette are eliminated.
- Large color graphic screen that can be read in direct sunlight.
Pyxis Lab has a Continuous Improvement Policy, this means that this units specifications are subject to change at any time and without notice. However, it is only for the betterment of the unit! The Fluorescent Polymer concentration scale is based on the polymer containing 0.25 mole % fluorescent monomer.

ST-700 Inline pH / ORP / Conductivity Sensor With Embedded Transducers
The Pyxis ST-700 series of pH, ORP, and conductivity probes are designed to simplify installation, calibration, and in-use operation in industrial wastewater and cooling water applications. These probes have an embedded 4~20mA transmitter.
The oversized platinum disk ORP and the flat pH bubble sensing elements increase resistance to contamination. The double salt bridge design with large junction capacity ensures a long sensor life with minimum maintenance.
Typical Applications
Industrial wastewater treatment, cooling water treatment
Features
- Dual embedded transmitters in sensor housing: 4-20mA and RS-485 supporting MODBUS.
- Large conjunction capacity (compared to replaceable electrode design) leading to longer service life.
- Longer maintenance cycles with high contamination resistance. Eliminates the need of pre-amplifier and transfer signal directly in 4~20mA or digital protocol.
- Enhanced robustness when controller is away from sample point.
- Specially designed pH/ORP electrodes tolerant to short time frozen during shipment or storage.
- Stainless steel solution grounding point on sensor to stay away from ground loop problems.

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.

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.
