PDA2000 Photometric Dispersion Analyser

The PDA2000 Photometric Dispersion Analyser is a simple, rugged, but very sensitive monitor for flowing suspensions and emulsions, based on an optical technique developed at University College London. The unit is compact and lightweight (width: 380 mm, depth: 200 mm, height: 140 mm, weight: 4.5 kg).

Applications include:

Selection of optimum flocculent dosages.
Control of dispersion and emulsification processes.
Assessment of the strength of aggregates (flocs).

Some of the advantages of the PDA2000 over more conventional techniques are:

Very simple to operate—little attention needed.
A very wide range of suspension concentrations can be directly monitored (from PPM levels to several percent solids).
No orifices to clog.
Minimal problems due to contamination of optical surfaces.
Flow-through operation, ideal for on-line applications.
Novel flow cell using inexpensive, disposable plastic tubing—no connection problems.

The PDA2000 Photometric Dispersion Analyser is now available exclusively via the joint Rank-Econovel website. Please visit the website for further information about the PDA2000.
