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.

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.

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.

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.

Made with metal additives, these balls test the sensitivity of food-processing metal detectors. They’re often used to calibrate metal detectors to find metal-detectable plastic tools that have fallen into a batch. To calibrate your metal detector, run different balls through the line—the smaller the ball, the more sensitive the detector must be to recognize it. Since they’re spheres, their orientation won’t affect a metal detector’s ability to register them. These balls help you comply with Hazard and Critical Control Point (HACCP) programs for food safety. They’re FDA compliant for direct contact with food. Balls are autoclavable, so you can sanitize them with steam.

This kit includes the hose, gauge, and fittings needed to charge an accumulator.

Check that your HVAC smoke detector is working properly. Wire these test stations to your smoke detector controller to test difficult to access smoke detectors from a convenient location. Indicator lights show if your smoke detector is powered on, if it senses smoke, and if its sensors are too dirty to detect smoke and need cleaning. These test stations activate with the turn of a key so you don’t turn them on by accident.

In a matter of minutes, confirm your earplugs deliver the right level of hearing protection. These kits help you meet OSHA standards for protection from excessive noise. Conduct the test onsite—everything you need, including a tablet with software already installed, is included. To use this kit, you will undergo a hearing test with and without your earplugs to determine the lowest volume you can hear. The system then calculates the difference between the scores and produces a personal attenuation rating (PAR).

Once the test is complete, you’ll receive a full report to help you choose the best earplugs. The results automatically upload to cloud storage and can be accessed on multiple devices.

Check your respirator for a tight seal—these testers help you comply with OSHA guidelines for respiratory protection. Performed at least once a year, fit tests make sure that a respirator is snug against your face and doesn’t leak. These testers use a bitter solution to test whether you can taste or smell it while wearing the respirator. They’re recommended for fit testing half-face respirators being worn near mild hazards. Keep wearing a respirator with the same manufacturer model and size once you pass a fit test, or you’ll need to test again.

Respirator fit testers that cannot be sold to Canada or outside the United States are restricted due to product regulations.
