AUTOMATIC SAMPLING DEVICE FOR SOIL PORE WATER

摘要

Provided is an automatic sampling device for soil pore water, which is capable of sampling soil water automatically at a desired time, by monitoring a water content of an outdoor soil of a soil solution sampler and an indoor negative pressure state, and monitoring whether the soil water is collected. The automatic sampling device for soil pore water comprises: a soil solution sampler (110) for sampling the soil water from a contaminated soil; a negative pressure setting part (120) for setting and maintaining a negative pressure inside the soil solution sampler (110); a flow system part (130) for injecting the soil water sampled from the soil solution sampler (110) into an analyzing container, and discharging the soil water after analyzing the same; and a controller (160) for controlling the soil solution sampler (110), the negative pressure setting part (120) and the flow system part (130).
