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.

Plating Controllers
Copper/Nickel Plating Controllers
Walchem’s WCU410 Copper Controller and WNI Nickel Controller are optoelectronic on-line analyzers that measure the actual concentration of copper or nickel in solution. They are used in a variety of applications including electroless plating baths and microetch baths (including oxide-replacement types).
Concentration Read in Units
- Selectable between grams per liter (g/L) or ounces per gallon (oz/gal).
- Backlit digital display also acts as a bar graph for a continuous “visual summary” of measurement versus set point.
Concentration set point, alarm set points (high and low), dead band and pump on time are all easily adjustable.
- An interlock feature allows external devices (such as a flow switch ) to interlock control relays.
Download stored data from the controller to a USB stick. Use the data to simply and easily validate system performance. The data and event logs show copper or nickel values, as well as accumulated chemical feed and relay activation times.
Four Separate Control Relays & Outputs (WCU )may be used to add copper, caustic, formaldehyde or chelator/stabilizer chemistries.
- Each output has a replenishment totalizer which may be set in units of time or volume.
Optional pH Input Board (WNI) may be used to add pH adjustment chemistry.
– Output has a replenishment totalizer which may be set in units of time or volume.SKU: n/a -
