Sieve Shaker – LCD

Advanced 3-Dimensional Sieving & Programmable Particle Size Analysis System

Althea Solutions introduces the Electromagnetic Sieve Shaker ALHES-201, a solid-state, microcontroller-controlled laboratory instrument specifically designed for the accurate and reproducible determination of particle size distribution in granular and powdered materials. Powered by an electromagnetic drive with no rotating parts, the ALHES-201 provides consistent sieving performance with low maintenance and low noise operation.

Featuring advanced 3-dimensional sieving motion, the ALHES-201 offers Continuous, Intermittent, and Logic operating modes, allowing users to optimize the sieving process according to different material characteristics and testing requirements. Its programmable amplitude, power level, and sieving duration provide precise control over the complete sieving cycle.

The ALHES-201 is equipped with a 7-inch high-resolution resistive touchscreen, digital parameter programming, internal data storage, password-protected user management, and an RS-232 interface. With a measuring range of 20 µm to 25 mm and support for sieve stacks up to 203 mm diameter, the system is suitable for applications involving sand, crushed rock, soil, grains, seeds, and other granular materials.
