The new patented measuring arrangement of the Camsizer – two digital cameras as adaptive measuring system – improves and refines the principle of digital image processing. A broad range of particle sizes from 30 µm to 30 mm can be measured with great precision, without adjusting the measuring range or any other adjustments.

There is a division of labour between the two digital cameras (CCDs) during the measuring process. The basic camera (CAM-B) registers large particles and the zoom camera (CAM-Z) registers small particles. While the sample falls past the light source via hopper and chute into the sample tray, the particles are measured optically without any contact. The non-distorted digital images produced in rapid succession by cameras are processed simultaneously by electronic means. In this way, many different particle distributions and shape parameters can be calculated precisely and quickly at the same time.
