The Delmhorst G-34 Hops Moisture Meter lets you easily check moisture levels in baled hops to assure high-quality harvest and safe storage. This meter has a moisture range of 7%-14% in hops. The large analog display and built-in battery check make this a favorite among hop growers worldwide. The G-34 meter cannot be used unless you purchase a Delmhorst Electrode, preferably the Delmhorst 30-E/C because it has 9" pins for greater penetration. Another good option for Hops is the 832 Long Pin Prod, which has 6 pins, each with 3 1/4" penetration.
