Cleaning the prism

In most applications the prism stays clean due to its self-cleaning effect.

In case of a coating problem, the preferred solution is to try to increase the flow velocity, for example, by installing a pipe portion with smaller diameter. If increasing the velocity does not provide a solution, consider installing a wash nozzle and a wash system. See PR53 Prism Wash System User Guide (M212808EN).

If the prism needs mechanical cleaning:

  • Clean the prism with a soft cloth or with a glass fiber brush, if the dirt is resilient.
  • Use water or if needed, a suitable solvent.
  • Dry the prism gently using a lint-free cloth, such as a microfiber cloth.
Do not rub the prism using sand paper, rubbing compound, wire brush, and similar.
Pay special attention to cleaning the prism when performing RI calibration.

Cleaning the refractometer
