Sprayer Calibration Calculator
Calculate your application rate in L/ha from nozzle output, forward speed and nozzle spacing. Plan tank loads for your field and find the exact speed to hit a target water volume.
Catch nozzle output by holding a measuring jug under one nozzle for exactly 1 minute at your normal spraying pressure. Use that reading as your nozzle output.
Calibration
Enter your nozzle output, speed and spacing to calculate the application rate.
Formula: L/ha = (nozzle ml/min × 60) ÷ (speed km/h × nozzle spacing cm)
Job Planner
Complete calibration above first, then add field area and tank size.
Target Speed Calculator
What forward speed do I need to apply exactly X L/ha with these nozzles?
Uses nozzle output and spacing from the Calibration section above.
ISO Nozzle Colour Codes
Standard flat-fan nozzle outputs at 3 bar. Outputs vary with pressure — always check your nozzle chart.
| Colour | ISO Size | Output at 3 bar | ml/min |
|---|---|---|---|
Orange | 01 | 0.40 L/min | 400 |
Green | 015 | 0.60 L/min | 600 |
Yellow | 02 | 0.80 L/min | 800 |
Purple | 025 | 1.00 L/min | 1000 |
Blue | 03 | 1.20 L/min | 1200 |
Red | 04 | 1.60 L/min | 1600 |
Brown | 05 | 2.00 L/min | 2000 |
Grey | 06 | 2.40 L/min | 2400 |
White | 08 | 3.20 L/min | 3200 |
