Swap out Renishaw probe styles to inspect different features on a part without having to recalibrate. These probes mount magnetically to a base that threads into your coordinate measuring machine (CMM), making mid-inspection changes quick. They’re also known as modules. It’s easy to tell different styles apart from their different end colors. To take 3D measurements, they record the coordinates of different points on your workpiece. Because this involves physically touching your workpiece, they’re more accurate than other automated measurement systems. They’re touch-trigger probes, the most common CMM probe type, which means they stop to record the coordinates of one point at a time. Use them to check distances, diameters, right angles, and the location of holes and grooves. However, they're not as good at checking complex features, flatness, or roundness.

All probes require a stylus as well as a base (sold separately for some probes).

Trigger force is the amount of force required for a probe to take a measurement and record it. Choose a probe with a force that is high enough to avoid false triggers from vibration but not so high it damages the workpiece and leads to inaccurate measurements.

6W series probes work well if you need to inspect features on the bottom of a part, such as overhangs and undercuts. They measure in six directions instead of five.

MF series probes have a slightly higher trigger force than typical applications require to account for vibration.

EF series probes have the highest trigger force, so they’re the best choice for environments with vibration. They also work well for larger styli, such as long 5-star styli.

Installation tools make it easier to thread a probe base onto your CMM.
