Troubleshoot solenoid valves, check relays, and test permanent magnets by detecting if a magnetic field is present. Hold these detectors near a surface and they'll light up blue if they sense a magnetic field. They don't measure the strength or direction of the magnetic field.

Measure magnetic fields to determine electromagnetic interference and detect flaws in welded metal.

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.

Check for defects slightly beneath the surface of ferrous materials that you wouldn’t otherwise see. The yoke in these kits is powered by a battery, so it uses direct current to create a strong magnetic field that reaches just below the surface of your part. When you apply the powder, the powder will move towards any flaws, helping you identify tears, cracks, and other imperfections.

Ideal for fieldwork, these kits come with everything you need for on-the-go inspections. The yoke lasts up to eight hours on a single battery charge. Built for rugged environments, it has a sealed design that stands up to chemicals and other harsh conditions.

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.

Measure the strength of magnetic fields, electric fields, and radio frequencies at the same time. To detect emissions, just point these meters at the electrical equipment you want to test, such as a cable. When they detect high levels that could damage sensitive equipment, an alert appears in red and an audible alarm sounds. Their color LCD display shows readings, bar graphs, and trending graphs.

These indicators store up to 20 radio frequency readings. Send readings to your PC using a USB cable (not included).

These magnetic compasses provide your orientation relative to geographic points.

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.

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.
