Universal Surface Tester with high local resolution for deformation, damping, topography, micro-friction and many more

Universal Surface Solution within One System

UST® is designed to deliver quantitative mechanical characterization within one open platform. It serves best to the R&D center of our industrial partners and research institutes all over the world. Built on a patented measurement protocol, the UST® provides an essential and reliable solutions within the nanometer and centimeter range.

UST®– Universal Surface Tester, is the only open multi-modular system that provides a complete mechanical testing solution for the evaluation of bulk materials and surface coatings. Over 10 measurements can be accomplished and over 60 different test tips have been developed to meet the diversity of your characterization requirements.

The basic unit of UST® has two versions: UST® 100 (loading range 1mN-100mN) and UST® 1000 (loading range 100mN-50N). The basic unit consists of floor-stand cabinet, measurement head with 3 tips, automatic X-Y table and data acquisition system.

Among various kinds of commercial available in-line material property testing instruments, UST® is by far the only tester which closes the gap between the traditional macro-mechanical testing machines and nanoscale machines,  e.g. AFM.

  • High precision load sensor combined with piezo actuator and active feedback loop control for real-time measurement of normal load and friction force

  • Options with different load range by easy exchange of measuring head

  • Automatic X-Y table with built-in motor for high precision profiling, the measurement area is up to 60 mm × 60 mm

  • High resolution table for high repositioning

  • Accurate depth measurement with bigger travel range for all tests, up to 4 mm in Z direction

  • Advanced linear module with displacement sensor

  • In-situ measurement with local resolution

  • Steady control of speed, displacement and step load

  • Automated video microscope with synchronized panorama

  • Compatible to ISO, DIN and ASTM standards

  • Real time data acquisition with full integration of images, data and graphics

  • Easy sample preparation and tip exchange

  • Customized tip choice for various applications

  • Compatible with various environments: liquid, or humidity 


The UST® measurement procedure consists of a mechanically scanning by a stylus on the sample surface along a straight line several times. During this patented MISTAN® procedure, the stylus is moved on the surface either without load or with a defined load.

  • Step 1: Scan with no load. Surface structure is continuously determined.

  • Step 2: Scan on the same path with additional load to determine total deformation.

  • Step 3: Scan on the same path with no load to determine the elastistic deformation.

    Total deformation = Step 1- Step 2;
    Elastic deformation = Step 3 – Step 2;
    Permanent deformation = Step 1 -Step 3
