This product is used for sampling cylindrical root systems with a diameter of 20cm and a height of 20cm.
The lower part of the instrument is a cylindrical sample chamber with an inner diameter of 20cm and a height of 20cm. Four circular tubes are connected to the upper circular platform around the sample chamber, and a hollow tube is connected in the middle. The hollow tube passes through the circular platform.
When sampling, use a hammer to evenly strike the circular platform and drive the sample chamber into the soil. Take out the sampler from the soil and use a cylindrical sample push rod to push the sample out of the sample chamber through a hollow tube.
