SD-II Electric Aggregate Sand Equivalent Tester

Complies with the technical requirements of the “Test Procedures for Aggregates in Highway Engineering” JTG 3432-2024. The specimen cylinder is subjected to transverse linear oscillation via automated mechanical vibration, enabling determination of the sand equivalent value of fine aggregates and assessment of the relative content of clayey materials, thereby evaluating the cleanliness of fine aggregates. Performance features: dual‑tube operation allows simultaneous parallel automatic oscillation of two specimens, and a single button press automatically completes one oscillation cycle.
