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.

6-lb. yokes are lightweight and fit comfortably in your hand to reduce fatigue over extended use. 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.

Yokes with an AC/DC switch can also operate on DC power. DC power generates a deeper magnetic field than AC power to find defects underneath surfaces, such as internal tears and cracks.

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

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.

More sensitive than natural light kits, these kits use UV light with colored dye to detect cracks, seams, and pores on machined surfaces.

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.

Reveal leaks, cracks, and contaminants that you wouldn’t find with a typical flashlight. These flashlights use UV light to illuminate fluorescent dyes, particles, and other chemicals.

Make surface defects stand out—these flashlights have a UV light that illuminates fluorescent dyes, particles, and chemicals so you can identify cracks and pores on parts or find leaks in your system. These flashlights also have a white LED bulb that shines a focused, even beam for normal flashlight uses. The head bends up to 90° so you can direct light where you need to when holding them in tight spaces. A strong magnet on the opposite end lets you stick them onto magnetic surfaces for hands-free use.

Detect leaks and contamination while keeping both your hands free. These headlamps use UV light to reveal dyes, particles, and chemicals with fluorescent qualities, making cracks and defects easy to spot. Each headlamp also has a regular LED light to see in dim and dark areas. Both bulbs emit a focused, uniform light beam that works best for close-up inspections.

Headlamps with a motion sensor switch between brightnesses, beam patterns, and bulb types with a wave of your hand. They’re helpful when your gloves are oily or dirty. You can also press a button to switch between these modes. The additional bull’s eye beam pattern has a wide angle to illuminate at a distance.

Shine UV light over large work areas to uncover leaks, cracks, and contaminants. These lights illuminate fluorescent dyes, particles, and other chemicals, making defects easy to spot. Fasten them to a wall or ceiling, so you’ll have both hands free to adjust what you’re inspecting or make repairs.

Lights with ultraviolet LED bulbs last longer, are more efficient, and generate less heat than lights with fluorescent bulbs.

The combination of UV light and magnifying lens lets you see the smallest traces of fluorescence while inspecting. These lights cannot be sold to Canada due to local regulations on mercury content.

This light has two UV bulbs and two fluorescent bulbs that work independently of each other. The combination of UV light and magnifying lens lets you see the smallest traces of fluorescence while inspecting. This light cannot be sold to Canada due to local regulations on mercurcy content.

This versatile light can be secured in the stand or removed for hand-held use. A switch lets you select between UV and white fluorescent light. These lights cannot be sold to Canada due to local regulations on mercury content.

Use these lamps for UV curing as well as leak detection, quality control inspection, and testing. They cannot be sold to Canada due to local regulatory limits on mercury content.

Designed for UV curing of small areas, these lamps also aid in leak detection, quality control inspection, and testing. They cannot be sold to Canada due to local regulatory limits on mercury content.

Set the lamp on a bench top and the 360° rotating head directs light where you need it. It cannot be sold to Canada due to local regulatory limits on mercury content.

An optional lens filter (sold separately) lets you see extra-fine particles by reducing glare and the output of visible light.

Cover large areas with this long lamp. Use for UV curing as well as leak detection, quality control inspection, and testing. They cannot be sold to Canada due to local regulations on mercury content.

Wire terminals allow you to connect these bulbs to a power source through a panel. These bulbs are sized to fit into tight spaces such as signs, instruments, indicators, and flashlights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Ultraviolet LED bulbs are often used to sterilize surfaces, cure adhesives, and detect leaks. Ultraviolet light is invisible to the human eye.
