Fig. 2. Photograph of the equipment specifically made for soil dielectric measurements: internal stainless-steel electrode 0.003175 m in diameter and 0.16 m in total length with 0.152 m projecting above the chemical resistant Delrin probe head at the base (A), outer brass tube, 0.156 m long with an internal diameter of 0.085 m (B), retaining nut fixing B to E (C), male connector (D), microwave electrical connector (E), coaxial cable (F), syringe assembly for mixing suspension (G), mixing rod (H), syringe used to draw fluid out of the coaxial cell (I). A similar syringe was used with a piece of Tygon tube to connect to G, to apply a tension to deair the suspension.
