RED, I have to agree with Skinnbone, go with the so called "Elevator Mounted Unit" for the moisture. This unit has a cavity that collects the grain to get the moisture and when it gets full a proximity switch turns on a small auger that returns the wet grain to the paddles that are going in the down direction. Also if you go with this unit, I had where I would get a 5% moisture reading and this was a bad ground on the moisture plate. Just had to scrap the little ground cable to get a correct reading. Hope this is of help. ask if you need more. Jack in MN
