のテンシオメーター。[Scope of Claim for Utility Model Registration] (a) A U-shaped mercury manometer with different diameters on the left and right sides has the lower end of the measuring tube 3 bent into a U-shape, and a mercury reservoir 4 with an inner diameter of about 10 times or more larger is attached at the end of the lower end of the measuring tube 3. , fixed to a post 6 with a scale. (b) For the soil moisture tension sensing section, a porous porcelain tube 8 is glued to the lower end of the hard resin pipe 7, and a T-shaped pipe joint 9 is glued to the upper end of the pipe. The lateral opening of the T-shaped pipe joint 9 is used as a connecting port 10 for a U-shaped mercury manometer with different diameters on the left and right, and the upward opening is used as a water inlet 11. (c) Connect the upper end of the measuring tube of the left and right U-shaped tube type mercury manometer with different diameters to the communication port 10 of the soil moisture tension sensing section using a pressure-resistant hose 12. A tensiometer for measuring soil water tension, consisting of the above devices.
