unfortunately it is for the Early Riser 3 monitor system on 1200 planters. All of the sensors on the page you linked at Shoups are for SeedFlow or Early Riser... kind of misleading on their part IMHO. The sensor you ordered does not fit or work with the Pro600 or Universal Display monitors. The part number is 392257a1.
