THE PRODUCT LINE

The microhardness testers in the M/CROSCAN range automatically carry out Vickers testing and obtain hardness profiles in accordance with ISO standards. Being completely independent of any operator subjectivity, the measurement results assure the reliability and repeatability required by modern industrial processes.

The MICROSCAN line consists of instruments of high technology, equipped with highly interactive software, which allows their easy and immediate use even by operators with no specific programming or metrological experience. They are adapted for testing on large-size samples. The modular design of hardware and software developed in Windows environment, and the standard accessories, which are available, allow the system to be built up with increasing automation content, so as to cover a wide range of industrial applications.

There are three main versions of the MICROSCAN, working in compliance with ISO standards:

1. **The Microscan OD:** Microhardness testers that automatically produce indentations, manually carry out indentation measurements by means of digital micrometric eyepiece, and automatically establish microhardness value.
2. **The Microscan AC:** Automatic microhardness testers with manual specimen holder crosstable, developed on the basis of an Italian National Research Council version (C.N.R. 67181 A/84) patent: this version automatically carries out the measurement of Vickers and Knoop testing.
3. **The Microscan AC Plus:** With add-on modules that allow to carry out sequences of microhardness testing (linear and zig-zag profile, hardness map on x-y axis) in very fast time and with easily displaying results directly prepared by the customer itself.

Like all Galileo hardness and microhardness testers, the Microscan systems can be certified according to Italian Calibration Service (S/T) standards. Since 1987, LTF Centre has been approved by SIT as a Secondary Calibration Centre for hardness and microhardness testing. LTF certificates have technical and scientific validity within Italy and are also recognized by the other National Calibration Services making up the EAL, European Cooperation for the accreditation of Laboratories.

- **The MICROSCAN OD system:** The basic version of the automatic microhardness tester with column, allowing tests on very large size samples. They allow the Vickers and Knoop (optional) microhardness testing of a sample by measuring the dimensions of an indentation automatically produced by the device itself. Indentation measurement is carried out manually by means of a high-precision digital micrometric eyepiece. The electronic manages the results and gives statistical results such as average value, standard deviation, max and min. value, and number of measurements; further it allows the conversion of hardness value in a different scale unit as well as in the resistance to tensile stress (N/mmq). By serial, parallel, and keyboard emulation interface it is possible to export the results forward remote peripherals and directly in main Microsoft software packages. The system is easily upgradeable to more evolute versions.

- **The MICROSCAN AC system:** Establishes the Vickers microhardness of a specimen by automatically producing an indentation and measuring its characteristic dimensions. This feature combines the advantages of Vickers testing (extremely high sensitivity and extended range of application) with a reliability and rapidity comparable to Rockwell testing, in absolute accordance with the method laid down in the ISO standards.

- **The MICROSCAN AC Plus system:** Distinguished by a higher degree of automation and greater operational flexibility. These characteristics are obtained thanks to the following add-on modules: digital micrometer and software package for hardness profiles, zig-zag, array. Specifically, microhardness profiles can be very easily carried out by means of the digital micrometer, fitted on (x) axis of the specimen holder crosstable, with direct computer reading of the corresponding coordinate, and a dedicated software package. The software allows interactive programming of a sequence of microhardness measurements (hardness profiles zig-zag, array). Definition of the test point coordinates can be achieved either by introducing the appropriate numerical values from the keyboard or deriving the coordinates themselves directly from the electronic digital micrometer.
