Abstract

       The method for estimating the volume median diameter (VMD) of droplet generator, by sizing of partical image on monitor screen, has been applied and validated. The magnesium oxide-coated slide sample were analyzed by using eyepiece camera to output a digital image to monitor. Hand-drawn graticule, which was drawn and calibrated by comparing the stage micrometer scale, was used for measuring size of droplets. Data of droplet size classification was organized as an input file of the ststistics software (Excel, SPSS), to reach volume median diameter. This method gives similar results and offers severai advantages over conventional visual microscopic method. It's a good tool, less time consuming, for the operators who for public health pesticide applicators.
