Styli and accessories for metrology – precision and variety from itp
itp offers a comprehensive selection of styli and accessories in a variety of material combinations for all standard threaded connections. The range includes straight, star, cylindrical and disc-shaped styli, as well as extensions, adaptor plates, calibration spheres and other high-quality accessories. All products are fully compatible with all known CMM and CNC measuring systems, ensuring the highest levels of precision and reliability in metrology.

Straight Styli
Straight styli are the simplest and most commonly used type of stylus. They are suitable for inspecting simple features with which direct contact can be made. "Single-stepped" or multiple-stepped stems can be chosen depending on the task. All the probes in this category, except for pointed ones (type K), have a ball as a probing element. All standard materials for the components and their properties can be found in our material overview. The stylus pointer (type K) has a hardened stainless tip or a tip made of tungsten carbide with different conicity as probing geometry.

Star Styli
Star styli is one of the most versatile types of stylus. They allow the measurement of large diameters without the risk of bending, even with very long gauging lengths. They are the perfect solution to measure undercuts or threads. The wide range of variations and the number of fixed probe arms allow the generation of task-specific measuring programs. For example, if there is no probe in the stem direction (type W), a measurement close to the bottom of the hole is realized.

Cylinder Styli
The cylindrical styli come in use when the optimal measurement point cannot be reliably reached with the ball. For example, getting the endpoints of the punched holes in the metal sheets is essential during the scanning. This task can be accomplished by deliberately touching the stem of a cylindrical stylus. Please note that the probe´s axis must be as possibly perpendicular to the element´s axis. For cylindrical probes with rounded ends, it is also possible to perform end-face probing or probing on the entire ball area.

Adaptors / Holders
Adapters and holders belong to the 'Connecting Elements' category and allow different stylus shapes and types to be combined. For instance, star styli can be easily assembled using these components. They are an absolute "all-rounder" when it comes to "support" for complex stylus configurations, whether an angled stylus requires a specific rotational orientation or a rigid 90° stylus orientation.

Hemispherical Styli
Hemispherical styli are suitable for measuring elements requiring a large diameter of the probe ball with low weight or reduced overall height, as opposed to disc styli, which only allow radial probing. The hemispherical stylus can also be used to measure the stem direction. The advantage is that the entire surface of the hollow hemisphere can be used for probing.

Extensions
Extensions allow the stylus to reach into hard-to-reach areas of the workpiece or to keep multiple styli apart so that they do not interfere with each other. According to the metrology rules, extensions should be as short and rigid as possible, and the number of connection points should be reduced to the minimum.

Accessories
itp offers a wide range of different accessory components: e.g., certified calibration spheres, hand tools, or thread-measuring gauges. All accessories relevant to a measuring task are integrated with the standard program.

Disc Styli
Spherical disc are sections of a precision balls, available in different thicknesses and diameters. Such styli come in use where it is necessary to realise the measurement of large inside diameters or the integrated undercuts. Important note: Normal disks are unsuitable for probing in the Z direction (except discs with radius end rollers).
