In addition to the AS 200 basic, the series includes several advanced models to meet different application needs. The AS 200 digit cA is ideal for applications requiring controlled amplitude, digital parameter display, and interval operation, while the AS 200 control offers full digital monitoring and storage of up to 99 SOPs for routine and standardized analyses. For larger sieve diameters, the AS 300 control provides the same advanced features with a significantly increased sieving surface. For high-capacity applications, the AS 450 control supports sample loads up to 25 kg and combines electromagnetic precision with CET technology for maximum reproducibility, whereas the AS 450 basic serves as a cost-effective solution for reliable sieving of larger quantities, both in dry and wet conditions.
