Here’s an oldie-but-a-goodie filmed in New Hampshire in June, 2014. It’s something to keep in mind when you’re getting your sprayer ready for spring service. We were at a train-the-trainer event when someone asked:

If pressure is critical to spray quality and rate, how do you know if your gauge is accurate?

A great question, and it’s certainly true that pressure plays a big role in a successful application. You can head over to this article to learn about testing for pressure drop (which is less of an issue on airblast sprayers unless using very low pressures) and similar concepts.

Hopefully, this short video provides an answer.

Thanks to Chazzbo Media and Penn State Extension for making an unscripted and spur-of-the-moment concept into a polished video!
