Abstract: A soil sampling measuring device for collecting and measuring samples of soil for testing the volatile organic compounds in the soil. The soil sampling device includes a tactile indication of the volume of soil collected in the sampling device so that a person using the soil sampling device can determine when a desired volume of soil is collected in the soil sampling device without the need to refer to a visual scale. The soil sampling device includes a barrel and a plunger in the barrel, with at least one of the plunger and the barrel adapted to provide a change of resistance between the plunger and the barrel when the plunger is extended or retracted through the barrel which provides a tactile indication to the user of the soil sampling device that the plunger has reached a desired volume within the barrel. For example, the barrel of the device may include a rib or groove which respectively increases or decreases the friction between the plunger and the inner surface of the barrel.

Abstract: A soil sampling device for collecting samples of soil provides a single use unit with an integrally molded plunger. The soil sampling includes a cylindrical body having first and second ends, with the body comprising a cylindrical wall having a longitudinal axis and an end wall. The cylindrical wall extends between the first and second ends of the body, with the end wall being positioned at the first end of the body. The second end of the body defines a mouth which is adapted for inserting into soil. A piston is positioned in the body, and the end wall includes a projecting member extending outwardly from the body which defines a plunger. The end wall includes reduced cross-section around the projecting member and is adapted to break when a force is applied to the projecting member to thereby permit the plunger enter into the body and thereby push the piston along the longitudinal axis to expel a sample of soil collected in the body.
