Features

Accurate Sizing over an extremely wide 0.1 to 2000 micron range. Rapid Measurements at acquisition rates of up to 10 kHz capture the dynamics of any spray process in exceptional detail. A Patented High Concentration Analysis delivers accurate spray results at spray concentrations where other techniques would simply fail. Automated software and advanced analysis features ensure repeatable aerosol measurements can be made, time and again.
