The G-7 is a rugged resistance-type meter, great for testing the moisture content of grain at harvest time and while in storage. The integral double-disc electrode cup holds only 3-4 grams, allowing for more uniform sampling and providing accurate and repeatable readings. You can even attach optional accessories to check moisture in bulk material and hay. The G-7 also provides useful statistics on stored readings.
