Magnaflux, a leading manufacturer of non–destructive testing (NDT) equipment, offers a
complete line of spotcheckers for magnetic particle testing. These portable, easy–to–use units
provide a quick, reliable method for detecting surface and near–surface indications in ferrous
materials. Magnaflux spotcheck are available in a variety of models to meet the needs of any
NDT application.
Magnaflux spotcheckers use magnetic particles to detect indications on the surface of ferrous
materials. A magnetic field is generated by an electromagnet in the spotchecker, which
attracts the particles to the surface of the material being tested. The particles are then visually
inspected for indications, such as cracks, voids, or inclusions.
Magnaflux spotcheckers are available in a variety of models, each designed for specific NDT
applications. The basic model is the Spotchecker 1, which is ideal for general–purpose testing.
The Spotchecker 2 is a more advanced model that offers increased sensitivity and additional
features, such as a built–in light source. The Spotchecker 3 is the most advanced model,
offering the highest sensitivity and a wide range of features, including a digital display and
data storage. Magnaflux also offers a variety of accessories for its spotcheckers, including a
carrying case, an AC adapter, and a variety of different sized magnets. Magnaflux
spotcheckers are backed by a one–year warranty and are available through a network of
authorized distributors.
