    Calibration Spheres for CMMs

    Image of Product. Top orientation. Contains Annotated. Calibration Spheres. Calibration Spheres for CMMs.
    Test your coordinate measuring machine (CMM) probe and stylus against a precise reference point before you start inspecting. These spheres come with a calibration certificate traceable to UKAS (United Kingdom Accreditation Service) that confirms their accuracy. Made of tungsten carbide, they won’t lose their precise shape or size over time.
    To prepare your probe for different inspection angles, adjust the angle of the sphere. For example, if you need to measure underneath a part, angle these spheres down to 45°. They rotate 360° even when angled. They snap into place when they’re perfectly vertical, the most common position. After you’ve positioned these spheres how you want, lock them in place by tightening the collar. Each time you adjust the sphere, you’ll need to recalibrate your probe and stylus.
    Smaller spheres are best for probes with smaller stylus ends. As a rule of thumb, you should use the 25 mm dia. sphere for any stylus with an end diameter over 2 mm.

    Metal Detector Calibration Kits

    Image of Product. Front orientation. Metal Detector Calibration Kits.
    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.
