When I find my equipment is spraying just right, I grab a pocket thermometer. With a variety of elements including sun and fluctuating temps outside, that’s what I use to maintain the temperature between my gun and proportioner.
I always stick a pocket thermometer at the halfway point of my hose, so if there’s 200 feet I stick it in the sleeve at 100 feet. This way, if the material sprays a little off, I just check that thermometer to ensure the hose is the same temp all the way through.
