Spraying Systems Co. utilizes commercially available Viscometer (Brookfield brand) and Tensiometer (EasyDyne brand) instruments to characterize material density, viscosity, and surface tension. These instruments may be used for a material assessment alone, or as part of a non-water spray test to assess the material qualities prior to spray characterization. These instruments also allow tests to be conducted with target rheological properties and mixing ratios to be tested for appropriate results.
