The testing device for complex automatic measurements of agricultural nozzles (Fig.1), and some tests methods are presented. The developed methods provide information on the individual parameters of spraying quality of each studied nozzle. Results of those studies has been recorded in the electronic database, and then analyzed by means of a computer program which will also make it possible to eliminate faulty nozzles. Besides, results of the estimation for the nozzles considered to satisfy the requirements of the standards but examined on a 50 mm grooved table (according to the ISO standard 5681-1:1996) has been subjected to conversion to the requirements of the grooved table (100 mm). Differences results CV for virtual paternator and laboratory paternator tests were obtained: 0,4 to 3,1 percentage point.Conversion of the results will be performed by of the prepared computer program and adopted to practically use sprayer booms of agricultural nozzles (virtual paternator). This program will also determine the sequence of placing the nozzles on the spray boom. Program environment “R” is used on conversion of results.
