Capabilities

DropVision® provides users the ability to analyze hand held sprayers and truck mounted sprayers but goes beyond anything offered by any other provider. DropVision® is able to analyze slides for aircraft characterization and slides positioned at far field drift distances downwind of the release point of a spray cloud.

DropVision® Process

DropVision® consists of a specialized high eye-point compound microscope with a built-in hi-resolution digital imaging processor; DropVision® Advanced Droplet Image Analysis software; and the DropVision® Graphing & reporting software. Using conventional sampling techniques such as a one inch or three millimeter teflon slide wave, field spinning impingers or any recognized droplet sampling technique, droplets are deposited on the slide. The slide is placed on the microscopes mechanical stage. DropVision® electronically captures images of the slide, analyzing each droplet while eliminating any background objects, coalesced droplets or nonqualified droplets through advanced proprietary image analysis algorithms. DropVision® rapidly analyzes and reports the new EPA label requirements, providing the user with standards such as DV.1, DV.5, DV.9, droplet densities per mm2 and relative span.

Tremendous Time Savings

DropVision® is more efficient than conventional slide measuring techniques that take up to 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.

DropVision® can analyze and 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.

Statistical analysis of DropVision® compared to conventional human eye-read and analyzed measurements demonstrated superior results. It should be noted that DropVision® through the proprietary image analysis algorithms measures droplet sizes as finite as one pixel (<1 micron). This advanced and unmatched measuring technique produces a more precise and accurate measurement of droplet sizes as compared to conventional methods. DropVision® produces a comma delimited ASCII text file that is easily imported into Microsoft1 Excel2 for further analysis. Each field of information is labeled and simple to interpret.

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 and 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. 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 Excel or Excel-compatible files?

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. Product Literature.
