The Cleanalyzer is a high-end analytical system designed to examine particles on filters – a key procedure in performing reliable and reproducible evaluation of component cleanliness.

Precision mechanical parts machined to exact tolerances are susceptible to damage or malfunction caused by particulate contamination. To address this issue, component cleanliness must be measured, and quantified in order to guarantee full function and to avoid failures due to particulate damage. The Cleanalyzer system is a powerful, fully integrated test platform which enables precision measurement, analysis and documentation of this critical cleanliness indicator. Cleanalyzer is fully compliant with all current particulate standards.

The currently valid standards were integrated into the specialized measuring software.
