1Instrument features

This equipment is a testing device used to inspect the performance of products manufactured by manufacturers. Composed of programmable controller, touch screen, force sensor, transmission device, onboard printer, etc., it provides menu display in both Chinese and English, and has human-machine dialogue to set various parameters for automatic operation and testing mode. Automatic judgment based on test results,And the test data and results will be printed out by the printer for analysis.

2、 Testing principle:

determinationThe rupture strength of the membrane is determined by fixing a piece of the tested prosthesis sample onto an elastic membrane using a flat ring fixture, and increasing pressure underneath the membrane until the sample ruptures.
