Tester di resistenza alla trazione JJNCT

di tensionedi carico in trazionedi propagazione di fessura

JJNCT Notch constant tension testing machine Overview The tester is used to measure the tensile stress cracking performance of notched plastic sheet under specified test environment and constant tensile load. Standard ASTM D 5397 Characters 1.Six units can be tested independently, easy to operate, accurate and reliable. 2.Six-unit design, five stations per unit, extremely high test efficiency. 3.The system has automatic water replenishment function, dual stirring motors make the temperature fluctuation in the bath smaller, and the circulating flow channel makes the temperature field more uniform. 4.The glass cover device between the sample holders helps prevent water vapor from evaporating and facilitates the observation of test conditions. 5.Automatically control the temperature of the medium, automatically control the height of the liquid level, automatically record the breaking time, print test data and other functions. 6.With abnormal temperature or liquid level alarm function.
