DORAN Grain Grader

Proven design and best-in class features

Introduced in 1976, GrainGrader™ was the first grain-grading scale — setting the standard for performance, durability and affordability — and after 45+ years continues to define excellence.

The GrainGrader™ has a 110 VAC filtered power supply to reduce the effect of normal line noise and 100% overload protection and is designed for accuracy, efficiency, and quality control. Plus, superior build quality and all-stainless construction makes the GrainGrader™ easy to clean and provides outstanding long-term value.

Best-in-class features give operators pinpoint control to calculate dockage (foreign material) percentage; and determine weight in pounds per bushel or kilograms per hectoliter.

Easy set-up for any requirements: standard or reciprocal percentage; cup selection in quart, pint, or liter; active or frozen percent; and test weight. Samples can be stored in Memory. The optional RS232 cable sends data to a computer or printer.

GrainGrader™ is on the GIPSA Approved Equipment list and is certified legal for trade by NTEP.
