Frac Sand and Proppant Size and Shape

How the CAMSIZER Works. The wide dynamic range from 30 μm to 30 mm enables the analysis of the entire dynamic range of any frac sand or other proppant. In addition to the size distribution the CAMSIZER analyzes the shape of the particles at the same time, providing accurate morphology data that is totally independent of the operator.
