Cleanliness standards for components and assemblies are rising constantly. This applies to numerous industrial sectors, such as mechanics, hydraulics, optics, pneumatics, automotive, etc. Current laboratory techniques for monitoring component quality according to VDA 19.1 or ISO 16232 are costly and time-consuming. Depending on the systems used, it may take hours or days before results are available. However, when it comes to high cleanliness requirements, fluctuations in quality need to be detected very quickly.

We have the solution you need to analyze particle sizes in liquids in a continuous automated process


Your advantages of in-line analysis with PuriCheck

  • Real-time monitoring of the quality and stability of cleaning and rinsing processes, as well as the development of closed loops
  • Analysis results are linked directly to components / batches by analyzing media quality after each cycle
  • Reliable detection of large single particles (so-called killer particles) in media circuits
  • Optional visual particle characterization
  • Ability to draw conclusions about component quality from media quality
  • Robust system, fully-automated if desired, which is also suitable for use with cloudy and foaming media
  • Can be integrated into existing systems and equipment or operated as a stand-alone solution
  • Robust and easy to operate

How PuriCheck works

PuriCheck combines filtration and analysis with an optical system and digital image processing in a single system that is coupled directly to the critical process relevant to cleanliness.

1. Particles are extracted from the test medium via an analysis filter


2. A test image is recorded


3. This is analyzed and the results displayed


4. The analysis filter is backwashed


5. A reference image is recorded


Next analysis...


The automated and fast process yields reliable measurements of technical cleanliness, very low blank values and high retrieval rates, rendering automated particle inspections in many cases on par with or superior to manual particle inspections in a laboratory environment.
