Condition: ready for operation (used), Year of construction: 2001, functionality: limited functionality, For sale is a Fischercope H100C XYp micro-/nano-hardness testing system by Helmut Fischer (year of manufacture: 2001). The device was last used in a laboratory, but is currently not fully functional and is therefore expressly sold as defective / for repair or as a source of spare parts. Known issues: - Table advance movement does not function correctly (the table is positioned under the measuring head, not under the microscope – precise measurement is currently not possible). Likely an electronic issue. Fedpfxoyu Nabe Ad Nopg - The measuring table moves independently to the left – possibly a joystick failure. - Indenter change does not work correctly (the probe does not move fully to the end stop). Therefore, the device is particularly suitable for: • Repair by individuals with electronics expertise • Sourcing of spare parts • Research / hobbyists The optical condition is good for its age.

Year of construction: 2008, condition: ready for operation (used), functionality: fully functional, Scratch testing device for characterizing the adhesion and scratch resistance of thin coatings and bulk materials The scratch testing method involves scoring the surface with a diamond tip under a constant or progressive load. During the scratch process, the specimen moves under the video system to examine the various types of damages caused by the tip and correlate them with the applied load. Fodpfeytrufjx Ad Njpg The images can be digitized and precisely mapped onto emission, acoustic, and load diagrams. This standard procedure enables the comparison of different coatings, substrates, coating thicknesses, surface preparations, and the scratch resistance of bulk materials. Features include an acoustic emission sensor, multi-pass scratch function (repeated scratching along the same track), friction force measurement, and the 2018 upgrade: new illumination system with analyzer, polarizer, 2 apertures and filters, plus high-resolution INFINITY 5X and 20X objectives, and lens holder with adjustment screws for easy tip/microscope calibration.
