TR Tester ET 01
For determination of Low Temprature Retraction
TR Tester, ET 01, for determination of low temperature characteristics
by the temperature retraction procedure according to ISO 2921
and ASTM D-1329.
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 pre
cooling period is included.
The computer controls both the temperature
rise and measures the length change of the samples. The results
are displayed in 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. |
