Hahn + Kolb: Roughness measuring devices for the new ISO standard 21920

All roughness measuring devices available from Hahn + Kolb have a robust aluminum housing and a touchscreen display. For a wide range of applications, dual feed units for skid and free probes as well as individual special solutions are possible. This allows users to perform more measuring tasks than with pure skid-mounted touch probes. In addition, the comprehensive Diavite range from Hahn + Kolb provides inexpensive probes for almost any measuring task, including ball probes, depth, bore and tooth flank probes as well as axis and cutting edge free probes - for example for value acquisition on deep-set surfaces, gears, grooves and bores as well as narrow recesses. The Micro and DH-9 models from Diavite are versatile measuring devices that meet every requirement in the workshop and measuring room. The Micro is an ideal entry-level device in terms of price and performance, while the DH-9 offers an even wider range of functions. Users can connect both models to a computer via a USB-C interface and thus master demanding measuring tasks. The Diavite App Light enables effortless value transfer and report generation. Compared to Micro, the DH-9 device has more roughness parameters and can also record profile values in addition to roughness values. A thermal printer is also integrated.

EasyRoughness from Atorn provides users with maximum performance. The measuring device even measures the roughness of delicate bores, shaft diameters, internal recesses and tooth flanks. In addition to a practical visualization of the surface roughness via a large 10.1" full HD industrial touchscreen PC, the measurement results are stored via the integrated Windows IoT operating system, including the option of image/photo documentation. The device also allows the connection of a commercially available printer and a barcode scanner for time-saving recording of recurring measurement tasks. Barcode scanners allow users to link a specially created measuring program, including all parameters, to a barcode and simply call it up to measure recurring parts. Images for adjusting the clamping situation can also be stored and shown on the display. The new international standard ISO 21920 with its three parts for profile measurement, characterization and specification of the surface condition (roughness, waviness) of components has replaced the withdrawn standards ISO 4287, ISO 4288, ISO 13565-2 and ISO 1302 since the end of 2021. These no longer covered all the possibilities of modern measuring devices.
