Stress Relaxation Testing Machine

1. Main Functions and Characteristics
The stress relaxation testing machine works in accordance with national standards GB/T5224-2003 and GB/T10120-1996. In the light of preset test parameters, it is able to automatically accomplish some testing procedures, including control, data collection, displaying and saving (major parameters, namely testing force, relaxation force, relaxation rate or logarithmic relaxation rate, and temperature). The product is capable of analyzing and processing test results, and printing test curves and reports based on your requirements. All the test curves demanded by these two standards are attainable, containing curves of time or logarithmic time and other parameters, such as remaining test force or logarithmic residual force, relaxation force or logarithmic relaxation force, relaxation rate or logarithmic relaxation rate, and temperature.
