The Molecular Sieve Crushing Strength Tester is a new type of testing instrument that utilizes high-precision sensor technology and features a digital display. Compact in design, small in size, and easy to operate, it is suitable for testing the crush resistance of spherical, rod-shaped, or cylindrical granular materials.
It is suitable for strength testing of samples such as fertilizers, pharmaceuticals, and catalysts.
Complies with the national standard GB/T 44750-2024 “Measurement of Compressive Strength of Granules.”
Granule strength testing involves applying gradually increasing axial pressure to cause a single granule to fracture, recording the maximum pressure it withstands before breaking as an indicator of strength. Brittle granules fracture when the pressure exceeds the critical failure threshold, while the compressive strength of different granule types is determined by analyzing the mechanical response characteristics during the loading process.
Equipped with a 3.5-inch high-definition LCD screen that displays test data and the user interface in real time, providing a clear and intuitive visual experience.
Features power-on self-test and automatic zeroing functions, utilizes a motor-driven screw pressure system, and is equipped with an intelligent overpressure protection device.
Equipped with a new-generation thermal printer, supporting instant printing of test results.
Human-machine interaction is more accurate and convenient.
Utilizes high-resolution sensor technology, supporting adaptive acquisition of precise pressure values based on different contact methods.
Strictly complies with the latest national standards and can test brittle spherical, rod-shaped, and cylindrical particles.
The instrument’s operating noise is below industry standards.
