A wide range of accessories, such as inline dispersers and cleaning cells, provide a so-called “process interface” for adapting the measurement probe to different conditions
within the process.

The option of dispersing the particle flow within the process vessel sets Parsum probes apart from other inline measuring systems. Inline dispersing is the only way of ensuring particle-size determination in damp, sticky, electrostatically charged or otherwise complicated materials in a reliable manner and in a way that is  comparable with laboratory processes.

The cleaning cells use  compressed air to keep the optics free of particle deposits, thereby significantly reducing the cleaning frequencies. Inline dispersers dilute the particle flow using compressed air, while simultaneously preventing deposits and blockages on the optics. A hard-chrome-plated protective tube means that the probe can be used even with particularly abrasive materials such as silicon, corundum and similar materials.
