This tester is used to evaluate the ozone resistance of vulcanized  rubber and thermo-plastic rubber while exposed  to static tensile strain, with air containing a definite concentration of ozone and at a definite temperature to examine  the  ozone  resistance  through  observation  of cracks.  The tester can also apply dynamic tensile strain as an option. To control the ozone consistency, the tester adopts the ultraviolet absorption  method.
