OverviewThe Leather Digital Lastometer GT-KC37A is a laboratory instrument for measuring the anti-cracking index of uppers, leather facings and thin leathers. It raises a bursting ball at a controlled speed and records the height increase at the moment of cracking.
Application- Determines anti-cracking index for leather uppers, facings and thin leather samples.
- Clamp frame secures the sample while a ball is raised at 12 mm/min until crack occurs; the recorded rise equals the crack value.

Product IntroductionThe GT-KC37A performs controlled, repeatable cracking tests by clamping a circular sample and raising a bursting ball at a fixed speed (12 mm/min). When a crack appears, the vertical displacement is recorded as the crack value, enabling objective comparison of leather resistance to cracking.
