High-sensitivity detection
Suits complex geometries and critical components.
Visible dye or fluorescent
Choose the system that matches your acceptance standard.
Manual to fully automatic
Scales from bench use to a production line.
Controlled process
Optimised chemical consumption and process control.
The liquid penetrant testing (PT) system detects surface-breaking defects such as cracks, porosity, seams and laps in non-porous materials. Based on capillary action, it gives reliable, repeatable inspection across a wide range of industrial applications, and is available in visible-dye and fluorescent versions in manual, semi-automatic and fully automatic configurations.
Applications
- Automotive components (gears, shafts, castings)
- Aerospace components
- Weld inspection
- Forgings and machined parts
- Valves and pressure components

Pre-washing station
The first and most critical stage: it removes oil, grease, dirt, scale and paint so defects are fully open and detectable.
Penetrant dipping and dwell
Components are fully immersed so the penetrant can enter cracks, porosity and laps; the dwell-to-dryer stage gives it the time it needs and dries the parts properly before development.
Developer cloud chamber and inspection
A fine, uniform developer layer draws the penetrant out so indications become visible; the inspection and unloading station is where parts are evaluated and cleared or rejected.
