DropVision®
What is DropVision®?
DropVision® is a droplet measuring system designed to analyze droplet spectra through image analysis of droplets contained on Teflon and magnesium oxide coated slides.
What are the components of DropVision®?
DropVision® consists of a specialized high eye-point compound microscope with a built-in hi-res digital imaging processor; DropVision® Advanced Droplet Image Analysis software; and the DropVision® Graphing & Reporting software.
How does DropVision® work?
Using conventional sampling techniques such as 1” Teflon slide wave, field spinning impingers or other recognized droplet sampling techniques, a sample slide is exposed to the aerosol cloud and placed on the microscope's mechanical stage. DropVision® electronically captures images contained on the slide, analyzing each droplet while eliminating any background objects, coalesced droplets or non-qualified droplets. This is accomplished by utilizing advanced proprietary image analysis algorithms.
Is DropVision® more efficient than manually reading slides?
Reading slides manually averages thirty-minutes for complete analysis of two-hundred (200) drops. DropVision® reads two-thousand droplets (2,000), produces the graphs and reports at an average rate of thirty-seconds, depending on the droplet densities on the slides.
Does DropVision® Analyze & Report the new EPA label language?
Yes. DropVision® provides the user with the new and current label language requirement standards. DropVision® specifically incorporates DV.1, DV.5, DV.9, droplet densities per millimeter squared and relative span.

Does DropVision® analyze more than one slide?
Yes. DropVision® can analyze one slide or multiple slides from multiple locations. DropVision® accommodates a single slide analysis or an unlimited number of slides and locations. This makes DropVision® very unique and capable of analyzing a slide for a single ULV fogger or aircraft calibration or a complex network of droplet measuring stations in a wide area ULV ground or aerial application. Product Literature.
How Accurate is DropVision®?
Statistical analysis of DropVision® compared to the conventional human eye-read and analyzed measurements demonstrated comparable results (refer to "The Comparison of Conventional Droplet Measurement Techniques & DropVision®"). It should be noted that DropVision® through the proprietary image analysis algorithms measures droplet sizes as small as one pixel. This advanced and unmatched measuring technique produces a more precise and accurate measurement of droplet sizes as compared to conventional methods.
What Output Data is produced by DropVision®?
The standard DropVision® Graphing and Reporting software automatically produces the following reports.
Does DropVision® Produce an Excel or Compatible File?
Yes. DropVision® produces a comma delimited ASCII text file that is easily imported into Microsoft Excel1 for further analysis. Each field of information is labeled and simple to interpret.
