@Dr. Anoop Srivastava, thanks for responding to this question. I normally used the infrared moisture meter to determine moisture content of fresh tomato fruits.
Typically, the measurement of moisture content (moisture content of grain or fruits, etc.) in a method such as using the oven, the weight difference dry and wet state will be the criterion for measuring the amount of moisture. So dry foundation is the basis of any method.
The moisture of a fruit (food in general) is usually express in wet basis (kg water/kg food), often in %. But in some fields (engineering) it should be express in dry basis (kg water/kg of dried food). Actually the values can be interchange.
