We speak to Dr. Christian Wichern from Nanofocus about their µscan Explorer Optical surface profilometer. This instrument is used for surface metrology and features a motorized stage, high resolution and fast scanning ability.
Paul Stewart from United Testing Systems demonstrated the ASTM D412 tension test on a rubber sample. He runs the test to determine the ultimate tensile strength of the material, demonstrates software control of the instrument and shows the results from the tension test.
John Guerin from Micromeritics shows us the AccuPyc II 1340 pycnometer, used for measuring the density of materials. John explains how the instrument works with the use of a schematic diagram.
Paul Stewart from United Testing Systems shows us their universal/tensile testing machines, pointing out such things as the various grips that can be used for different applications, different test specimens for tests such as tension, bend tesing and tear testing. He also shows us the Windows-based, USB user interface and let's us know what capacity machines they have available.
Tony Torsell from Anter shows us their Flashline 4010 instrument for measuring thermophysical properties of materials. This instrument can work up to 1600°C, in air, inert or vacuum atmospheres and can measure 5 samples at once.
Dr. Mariano Paganelli from Expert System Solutions shows us their high temperature optical measuring system. This instrument can provide thermal expansion data like a dilatometer, but has the added benefit that it uses optical techniques as opposed to mechanical measuring, so it can cater for non-rigid samples. It can also provide much more detailed information on a materials' behaviour when subjected to high temperatures.
Bob Fidler from Netzsch Instruments tells about the LFA 457 laser flash instrument used for measuring thermal diffusivity. With knowledge of thermal diffusivilty, thermal conductivity can be calculated.
