Reveal imperfections both at and slightly below the surface of your metal part, unlike other flaw detection methods. Use these particles with a magnetic yoke to check for faulty seams, welding defects, and fatigue cracks to make sure metal parts will be safe under high stress. The yoke creates a magnetic field that draws the particles towards flaws, making them easy to spot. To prevent issues with other inspections down the line, make sure to fully demagnetize your part to remove all the particles.

Use colored dye to reveal cracks and surface flaws in most nonporous material. Flaws become visible under natural light and appear as a bright red color. Commonly used for weld inspecting.

Find welding defects and other flaws in magnetic materials. These yokes create a magnetic field that draws magnetic powder (not included) to imperfections, making them easy to spot. All operate on AC power, which creates a small magnetic field ideal for detecting flaws along the surface of materials. Powered by standard electrical outlets, these yokes have a reliable and consistent power source.

Attach an LED light to your yoke to brightly illuminate inspection areas. They’re powered by the yoke’s magnetic field, so they don’t require batteries.

Calibrate your yoke before each use with a test weight to ensure accurate test results.

Create a high-contrast background for magnetic particles to make flaws easier to spot during inspections. This opaque white paint reduces glare, so you can see where particles are clustered around imperfections. No need for brushes—it comes in an aerosol can that’s easy to use during field testing and spot inspections. Even when the can is upside down, the 360° sprayer won’t sputter or spatter, so you can coat parts evenly without straining your wrist. To speed up inspections, this paint dries quickly, leaving a clean coat that won’t bubble or flake. It works with both wet and dry magnetic particles.

Find faulty seams, welding defects, and other surface-level flaws in ferrous materials. These kits come with everything you need to start inspecting parts. Apply the powder to the surface you want to inspect. Then plug in the yoke and it creates a magnetic field that draws the powder to the imperfection, making it easy to spot. Built for rugged environments, the yoke has a sealed design that stands up to chemicals and other harsh conditions. It’s also half the weight of a standard yoke and fits comfortably in your hand, so there’s less fatigue if you use it for extended periods of time.
