Fig. 4. 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, a similar syringe was used with a piece of tygon tube to connect to G, to apply tension to de-air the suspension (I).
