System for professional Cleanliness Analysis

Industry increasingly requires proof of the degree of cleanliness of components.
High demands in terms of function, quality and service life of the products call for

  • efficient, environmentally-friendly cleaning
  • Reliable, reproducible cleanliness analysis
  • Documentation of all analysis results

dhs Solution offers a complete analysis system for this: the dhs-Cleanalyzer®


Visual analysis of filters on which all of the particles are collected after the cleaning process

  • Processing of different filter materials and shapes
  • Processing of particle traps in addition with special adapter
    (preferably for model “Scan”)

Softwareanalysis with dhs-Cleanalyzer

  • Standards-compliant analysis as per VDA Vol. 19/V2, ISO 16232, ISO 4406,
    SAE AS 4059 etc.
  • Detailed presentation of measured values
  • Adjustable pre-classifiers (e.g. fibre criteria, coverage density as a percentage)
  • Immediate result checks (“live” evaluation tracking)
  • Short throughput times
  • Classification of all particles
  • Z measurement
  • Trend analysis option – long-term evaluations



Visualisation of all particles by means of a gallery view for:

  • A good overview
  • Working faster


Particle- and hall monitoring

With the help of particle traps set up in the production hall, particle precipitation can be detected at an early stage. Distracting effects which influence the cleanliness in the assembly surroundings can be investigatetd and judged so.

The dhs-Cleanalyzer® Scan evaluates the contaminated particle traps using VDA 19.2 (Illig value): sedimented particle precipitation from a wide range of locations and collection times is calculated and compared using a formula and summarised to give a measured value.
