Moisture Equipment

Moisture meters are used to determine the amount of moisture within grain presented for sale, a critical assessment of quality that affects the value and storability of the grain.  The Agricultural Marketing Service (AMS), Federal Grain Inspection Service (FGIS) uses the DICKEY-JOHN GAC 2500-UGMA and Perten AM 5200-A as Official Moisture Meters for all officially inspected grains and commodities.
