发明名称 Soil sampling apparatus
摘要 A soil sampler provides samples for on site disposition in forty and twenty milliliter vials for subsequent off site volatile organic analysis. A split sleeve contains a plunger positioned within the sleeve on a shaft to obtain a desired volume of soil when the sampler is thrust into the soil. An outer shell contains the split sleeve and a set screw device fixes the shaft and plunger in desired position within the sleeve. Metering marks on the shaft provide predetermined sample size indication.
