Low Temperature Retraction Tester (For Brittle Point test)
EKT-100TRB-Low
Temperature Retraction Tester is designed in accordance with ASTM D1329, ISO
2921 with fully automatic and computerized controlling system.
The system can automatically control the
temperature and measure the samples retraction by using high precision
measuring devices.
The system can hold up to 6 test samples. The
specimens’ elongation and immersion into
the cooling bath are carried out automatically.
The data, such as time, temperature and retraction rate, is simultaneously
displayed on the screen during the test.
Besides TR test, an extra function for brittle
point detection in accordance with ASTM D2137 is available as an option.
