Abstract
A moisture tester comprises a probe with a measuring head 1 and a probe carrier 2 comprising electrical circuits for deriving a value of the moisture content of the tested material. The probe comprises a body of insulating material 3 with a first rod 6 protruding therefrom and forming one plate of a capacitor, and additional rods 7 to 12 positioned in an open arrangement around said first rod and being interconnected with each other to form the other plate of the capacitor and to admit unhindered flowing of the material to be tested past said probe. Instead of two additional rods being mounted on plate 13 they may be mounted directly in the material 3. <IMAGE>
