Low Temperature Retraction Tester (For Brittle Point test)

Model : EKT-100TRB

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.
