The TR tester, Gehman tester and brittleness tester can be combined using the same base unit and a rig changing system.

The combined instrument consists of a base unit with a cooling bath and the electronics. The three different test rigs are then mounted on a carousel. No lifting is necessary when switching from one method to another. Windows applications for each method are also part of the tester.
An automatic computerized low temperature tester increases the precision up to 5 times. Also, the capacity increases by about 50 % and the labour time decreases by about 75 %.
Important specifications for all ET testers
