KES - G5 Compression Tester
The G5 Compression Tester is a precision testing instrument designed to evaluate compression characteristics of soft materials by simulating the sensation of human fingertip pressing. The tester accurately measures key mechanical properties such as compression hardness, compression work, and resilience. With a high-sensitivity force detection system, it can capture extremely small forces during initial compression and detect low recovery forces after deformation, making it suitable for detailed material texture and performance evaluation.
