Non Destructive Crack Detection

Cleanrooms, utilized in industries like healthcare, pharmaceuticals, and electronics manufacturing, rely heavily on High-Efficiency Particulate Air (HEPA) filters to maintain their stringent cleanliness standards. These filters, capable of trapping 99.97% of particles that are 0.3 microns in diameter, are subjected to regular tests to ensure optimal function and compliance with regulatory requirements. The tests help in early identification of filter degradation or failure, thereby facilitating timely replacements and maintaining the controlled environment's integrity, crucial for the successful operation of cleanroom activities.

The current state of the art

Crack detection for high-sensitive measurements is commonly performed through visual inspection or specialized techniques like dye penetrant inspection (DPI) or magnetic particle inspection (MPI), depending on the tested material.

Limitation & Challenges 

Extensive preparation


DPI needs extensive preparation and cleaning due to the use of liquid penetrant

 Ferromagnetic materials

MPI is limited to ferromagnetic materials and may require demagnetization.

Lack of Precision

Both methods may lack precise information on crack sizes or depths, necessitating additional testing.

Precise crack detection with Analytical Spheres


Analytical Spheres solution offers a unique approach using controlled spheres that infiltrate cracks, becoming visible under UV light. The color-coded properties provide immediate visual information about crack characteristics, enabling a comprehensive and efficient inspection process for detecting micro-cracks, even in complex geometries.

The advantage of the solution 

Enhanced Sensitivity

The small and defined size of the perfect spheres particles, acurately simulate the behavior of dust and airborne particles in real life scenarios.


Clear Visibility

The combination of low aggregation and color-coded particle sizes enables enhanced optical counting, and facilitate quantitative data collection.

Accurate Assessment

Analytical Spheres provide an innovative solution for identifying crack characteristics, facilitating efficient and accurate crack assessment.
