Moisture testing - Chapter 2 | Official Grain Grading Guide

Moisture specifications

The chart on the next three pages outlines the moisture specifications and, if the model 919/3.5' moisture meter is used, the conversion table number and representative portion required to determine the moisture content of each type of grain is provided.

Conversion tables are not available for all grains. The following information can be found on the CGC website.
