hydraulic bursting strength tester for medical face mask
To determine the bursting strength and distension at burst of woven, knitted and non woven fabrics, papers and boards by the application of hydraulic loading under a rubber diaphragm. The intelligent control algorithm gives accurate control of the burst time. Manual or automatic mode. Windows based software could analyze the test results and print, easy to operate. Different test areas can be accommodated allowing testing to corresponding standards.
