Calati 300AST vs ST300 – Leather Softness Measurement Comparison
In this video, we compare the Calati 300AST leather softness tester with the ST300, highlighting the key differences in measurement principles, calibration methods, and real testing conditions.
The Calati 300AST is designed to measure softness directly on the leather sample, ensuring stable and repeatable results through a two-step measurement process. Unlike traditional systems, it operates with a specific calibration method using a reference disc applied over the material thickness.
The ST300, on the other hand, follows a different reference approach, which can lead to variations if the calibration conditions are not properly understood.
This comparison demonstrates how both instruments behave under the same testing conditions, allowing operators and quality control technicians to better understand measurement consistency, reliability, and practical application in the leather industry.
Ideal for tanneries, leather laboratories, and quality control departments, this video provides a clear technical insight into softness testing methods and helps users choose the most suitable solution for their production needs.
