Test oils for magnetic particle testing
In non-destructive material testing (NDT), magnetic particle testing (MT) plays a central role in the detection of cracks and defects on or near the workpiece surface. In addition to the magnetic particle itself, the choice of a suitable carrier medium is crucial for a reliable and reproducible test result. Test oils for magnetic particle testing ensure optimum particle distribution and display quality - especially under demanding conditions.

What are test oils for magnetic particle testing?
Test oils serve as a carrier medium for the magnetic powder, especially in fluorescent or coloring suspensions. They are specially formulated oils with a defined viscosity, high flash point, chemical stability and low inherent fluorescence. Their main task is to distribute the magnetic particles evenly on the surface of the test part and to keep them in suspension during the entire test process.
These properties have a significant influence on the sensitivity, cleanliness and safety of the test procedure - especially in automated processes or tests with high quantities.
Advantages of high-quality PFINDER test oils for MT test equipment
Test oils for magnetic particle testing offer a number of advantages:
- Optimum suspension properties for uniform particle distribution
- High flash point for greater safety during handling and storage
- Low evaporation - particularly economical in continuous operation
- Low residue - easy cleaning of the tested components
- Stable viscosity - consistent test conditions
- Free of inherent fluorescence - very good and high-contrast displays
- Virtually odorless - pleasant to work with even over long periods of time
