GSF, Inc. operates as DICKEY-john’s exclusive national distributor for its commercial grain testing equipment. The majority of all grain elevators, seed companies and grain processors in the U.S. use a DICKEY-john GAC moisture meter in their operation. In 1998, the USDA/GIPSA/FGIS selected the DICKEY-john GAC2100 moisture meter as the new national standard for official grain grading.
