This sample collection device can be used to collect samples from soft ground by utilizing the residual holes from SS tests and others. A significantly large amount of samples can be collected. Additionally, by opening the lid of the collection device at a specified depth, it has become possible to collect samples with high precision at that depth. The use of hollow rods also allows for the measurement of groundwater levels. It is also possible to collect samples by direct penetration, not just from residual holes. ● For more details, please contact us or refer to the catalog.

This is a device for measuring groundwater levels using the remaining borehole after the SWS test. A PVC pipe is inserted into the borehole, and a cable with a sensor at the tip is inserted into the PVC pipe. The other end is connected to a tester for resistance measurement to detect continuity and measure the groundwater level.
