GrainMate is a simple-to-use grain moisture meter that helps farmers easily measure the moisture content in their grains before and during storage.  With GrainMate, farmers can accurately tell whether their grains are dry enough for harvest, storage or sale.

It consists of two parts: a hand-held reader and a metal probe. To measure the moisture content, all farmers have to do is insert the attached probe into a bag of grain, select the grain type and read the moisture content off an LCD screen.

They then compare the reading with an attached chart to know whether the grain is dry enough for storage.
