The WP4C chilled-mirror dew-point hygrometer is widely used for measuring soil total suction. This study aimed to evaluate its reliability in determining total soil suction through the vapor equilibrium technique. Results showed offsets between WP4C measurements of soil specimens and its correspondi...
