Tensile testing machine JJNCT

stress testautomaticfor plastic sheets

This instrument is used to measure the tensile stress cracking performance of notched plastic sheets in a specified test environment and a specified constant tensile load. Standard ASTM D 5397 Features 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.
