Motorised
hydraulic press for compression testing for loads not lower
than 300 tonnes equipped with a loading module with real-time
digital 4-digit display and with a memory circuit for storage
and display of the maximum value of the applied load. The
machine can be operated in manual and automatic modes. When
operated in automatic, the load can be applied in order to
produce stress increases as well as constrant deformation.
It is also possible to run automatically load and unload cycles
at constant rate of change either of stress or of deformation. |

| Universal
equipment with a load of 60 tonnes for tests on steel with
a loading module with real-time digital display and memory
circuit for storage and display of the maximum value of the
applied load. The machine can be operated in manual and automatic
modes, and can be used to produce stress increases as well
as constant deformation. It is also possible to run load and
unload cycles at constant rate of change either of stress
or of deformation. The equipment also has an XY recorder with
a sensitivity of 1 1mV/cm and 1MOhm for drawing stress-strain
diagrams (for tests under compression and traction) and load-deflection
diagrams (under flexural stress tests). Finally, the equipment
has a strain-gauge that may be used to create stress-strain
diagrams for steel. |

| Digital
thermo-analyser for thermo-gravimetric (TG) and differential
thermal (DTA) analysis of solid or liquid samples. By means
of these analyses it is possible to establish the amount of
any substance within the sample under examination that can
be thermally decomposed within a range of temperatures from
0 a 1200°C. The apparatus consists of a precision thermo-analyser
within an oven and a digital controller by which the thermal
cycle for the sample may be set and the mass-loss and sample
temperature increase and decrease may be measured with reference
to an inert material. |
