Amount of moisture in the grain expressed as percentage of the total weight of the sample, wet basis
M₀
Initial mass in grams of the test portion
M₁
Mass in grams of the dry test portion
Primary method
Method of grain moisture determination based on actual extraction of water either by convection heating (oven method) or distillation
Secondary method
Method of grain moisture determination based on some characteristics of the grain sample such as electrical resistance and capacitance which are related to moisture content and must be periodically calibrated against an official primary method
