How long are new sprayers well calibrated?

New sprayers that have been properly calibrated will maintain their effectiveness for a duration that typically correlates with the frequency and conditions of use, which often suggests that calibration could remain accurate until the sprayer is used one season. This is because factors such as wear and tear, changes in operating conditions, and potential blockages can affect the sprayer's performance over time. Regular maintenance and checks are essential to ensure continued accuracy, as calibration can degrade with usage or due to changes in environmental conditions. Thus, the answer reflects a realistic timeframe for the efficacy of the calibration without implying indefinite reliability or that maintenance checks of more frequency are the only way to ensure continuing performance.
