The new Gradex 3000 particle size analyzer from Rotex is designed to improve or expand quality-control programs by providing reliable, fully automatic sieve analysis for the gradation of aggregate material. Product can be analyzed more often and on a more timely basis, allowing for closer control of a full range of products. Highly consistent results are provided by the Gradex 3000 because the same shaking, brushing and weighing procedure is repeated on each sample. The Gradex 3000 also eliminates transposition and calculation errors by automatically classifying and weighing each sieve fraction, calculating and storing weight values.
