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.

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
One-handed operation. No vial or cuvette needed. One press to calibrate Pyxis ST-500 inline fluorometer via built-in WiFi.
Tolerance to interference
Auto-compensation for sample color and turbidity. Holds accuracy for a long period of time. No need for frequent calibration.
Durable and affordable
Fully dustproof and waterproof. Rugged structure to survive in a tough industrial environment. Affordable: start your fluorescent traced program today.

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-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.
