Overview & Regulation 
The instrument is built according to International Standards about fatigue, which describe test methods for the determination of the resistance of vulcanized rubbers under repeated deformations. This instrument permits to perform:
• Flex cracking/crack growth test
• Tension fatigue test.

According to test specification, the instrument can be easily adjusted by setting
• Test frequency (60 to 300 rpm)
• Test stroke (0 to 60 mm)
• The distance of the grips (up to 100 mm)
• The number of cycles before automatic stop can be set (up to 1.000.000)

Cooling system 
The instrument produced by Gibitre uses a Refrigeration Unit to reduce the temperature.
The use of the refrigeration unit, compared to cooling by liquid nitrogen, allows to:
• heck the test temperature perfectly, avoiding oscillations that may alter the results.
• Carry out long-term tests without risking to end the liquid nitrogen supply before finishing the test
• Eliminate the hazards related with manipulation of nitrogen
