bought another tester to have one at the farm and it showed 40 degrees lower than the old one. So I tested the new full strength and premix in the jug and it was way off.
Watch out for those things, this was the type that has the two pointers that float up.
I went to the five floating ball type.
What tester do you guys have confidence in?
