How to Calibrate a Handgun

  1. Measure and mark an area 18.5 feet by 18.5 feet square.
  2. Fill the sprayer up with water.
  3. Set the pressure at 35 to 40 psi.
  4. Set the desired flow rate of the handgun.
  5. Spray the area marked, keeping the time it takes to spray to wet the area.

How do you calibrate a handheld sprayer?

It’s simple

  1. Mark off a plot 18.5 feet by 18.5 feet.
  2. Fill the sprayer to normal capacity with water.
  3. Pump the sprayer to the pressure normally used to apply herbicides.
  4. Spray water over the plot area while maintaining normal and constant operating pressure.
  5. Record the time in seconds it takes to spray the plot area.

Why do you calibrate a sprayer?

Sprayer calibration provides the information you need to determine the amount of spray solution (both pesticide and carrier) being applied per acre. This information can help ensure you’re applying the amount of solution stated on the product label.

How often should pesticide sprayers be calibrated?

Equipment should be recalibrated periodically to compensate for wear in pumps, nozzles, and metering systems. Dry flowables may wear nozzle tips and may cause an increase in application rates after spraying as little as 50 acres. Improperly used agricultural pesticides are dangerous.

What does it mean to calibrate a sprayer?

The Real Definition of ‘Calibrating a Sprayer’ Sprayer Calibration Definition: To calculate and clearly understand the amount of liquid (spray chemical + water) you should apply on a certain size area. Remember: How fast you travel and at what pressure (PSI) you spray at equals the amount of chemical applied.

What is calibration of sprayer?

In practice sprayer calibration is a method to check end ensure that: 1. The volume of spray liquid mixed in the spray tank will fit exactly with the area to be treated – leaving no left over volume to be disposed. Calibration will prove if: − The nozzles are worn a little and the pressure needs to be readjusted.

How often should you calibrate a sprayer?

Sprayer Constants. There are four times when a sprayer must be recalibrated. The calibrated output of the sprayer will remain constant as long as ground speed, spray pressure, number of nozzles, and nozzle orifice are unchanged. Whenever any of these are changed, the sprayer must be recalibrated.
