What is sprayer calibration?

• A. The adjustment of a machine to make it deliver the right amount of spray or dry material to a given area
• B. A method for cleaning spray equipment
• C. A process for calibrating sprayer nozzles
• D. A technique for increasing tank capacity

Answer: (A)

Sprayer calibration is adjusting the spraying system so it delivers the exact amount of product to a defined area. This means setting the right nozzle flow and pressure, then considering how fast you move and how wide the spray swath is so the rate per acre matches the label. You verify the actual output by testing and calculating (often with catch cans or a scale) and adjust until the calculated rate equals the target. This ensures effective control, minimizes waste, and protects the environment. Cleaning the equipment, calibrating only individual nozzles, or increasing tank size won’t guarantee the correct applied amount.
