An automatic vibrating reed apparatus for internal friction and elastic mod
ulus measurements in solids is described. The apparatus is equipped with a
resistive heater for measurements up to 1400 K. A magnetic field (up to 250
kAt/m) is also available in the 300-1000 K range. Measurements as a functi
on of temperature and/or magnetic field can be easily carried out. Data acq
uisition is controlled by a computer and originally written software allows
automatic measurements and real time data analysis offering a user-friendl
y interface. The acquisition rate is nearly two orders of magnitude faster
than that achieved manually. The use of the analyzer is straightforward and
does not require a prolonged training of particularly skillful personnel.
