As a provisional monitoring device for geo-environmental aspect，a new-type of geo-environmental cone penetrometer is designed in this research . It consists of electrical conductivity（EC）sensor，pH sensor，water absorber and conventional CPT equipment. EC is continuously measured with depth. The value of pH is measured by absorbing water into the device. And using the same mechanism of absorbing water，it is also possible to pump up the water around the cone to the ground level.
　Because the water sampling port is set at the distance of 60cm above the CPT equipment，the ground water can be absorbed and collected efficiently with detecting the sandy permeable layer simultaneously.
