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.

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-700 Water Multimeter
The Pyxis SP-700 handheld multimeter measures six key water treatment parameters simultaneously: pH, conductivity, PTSA, fluorescein, ORP, and temperature. Featuring simple, one-handed operation, the multimeter leverages Pyxis proprietary technology combining electrochemical and optical measurements in a cuvette-less platform.
With the SP-700, you can view results in under a minute for all key parameters for a typical water treatment application such as cooling tower analysis. The multimeter logs a complete measurement history, which you can transfer via Bluetooth to your smart phone or PC for statistical analysis.
Custom product names and tracer/product ratios can be configured via Bluetooth-enabled devices.
For highest accuracy, the PTSA measurement uses our proprietary signal processing algorithms to compensate for sample color and turbidity conditions, which would otherwise cause erroneous readings.
SP-700 Features
- Breakthrough technology combines PTSA / fluorescein with conductivity / pH and ORP in a single, rugged one-handed meter.
- Proprietary pH / ORP module design with extra-large junction capacity provides increased service life and can be replaced without opening the meter enclosure.
- Intelligent sensor aging and pollution detection capability provides self-diagnosis during calibration.
- On-board storage lets you record up to 8 Gb of historical data with time stamp and options to set up sample location information.
- Long battery life enables 10,000+ readings.
