主要特点：
TR Tester, ET 01, for determination of low temperature characteristics by the temperature retraction procedure
according to ISO 2921 and ASTM D-1329.

The Elastocon TR Tester, has 6 test stations, is computerized and performs the test automatically after the cooling media has been cooled down and the samples has been mounted.

An automatic release of the samples, after the precooling period,
is included.
The computer controls both the temperature rise and measures the length change of the samples.
The results are displayed in a graph and TR10, TR30, TR50 and TR70 values are calculated.
The result can also be presented as a table with length change versus temperature.

The TR-values and the table values can be exported to other software such as spreadsheets.
As an extra option, an automatic cooling system with liquid Nitrogen can be supplied.
