The HARDI calibration Disk is a calibration tool to choose the right nozzle. Nozzles must show the manufacturers, type, ID number which relates to the colour and spray angle. The recommended spray pressures are shown on one side of the diagram together with the spraying speed of the agricultural machinery. In the other part of the diagram, the roulette wheel. First, you need to select your spraying speed and select the flow of the nozzle (l/min). Automatically, the type of nozzle and the pressure will be shown. The same thing can be done with the phone application MY HARDI. If you have already a concrete type of nozzle, you can also do the other way around and mark the volume of spray to use and the spraying speed and get the flow per nozzle.
