What pressure should be set at the nozzle tip when calibrating the output of a power spray rig?

Setting the nozzle tip pressure at 40 psi when calibrating the output of a power spray rig is important because this pressure typically allows for optimal performance in pest control applications. At 40 psi, the spray pattern is usually fine enough to provide effective coverage while ensuring that droplets are adequately sized for penetration and adherence to surfaces, which is critical when targeting wood-destroying pests and organisms.

In pest control, achieving the right pressure is essential for delivering the correct volume of product to the target area. Pressures significantly lower than 40 psi might result in insufficient coverage, leaving gaps in treatment areas, while much higher pressures could cause excessive drift or overspray, leading to inefficient use of the pesticide and potential environmental harm. Thus, 40 psi represents a balanced approach to ensure efficacy and safety in applying treatments against wood-destroying organisms.
