Hand Penetrometer — 1 m or 3 m

The hand penetrometer lets you measure soil resistance quickly and easily using your own body weight. To take a measurement, simply push the penetrometer into the ground with even force. The resistance measured at the cone is read from a pressure gauge with a red pointer.

The soil's actual penetration resistance (kPa/cm²) is found by dividing the reading by the cone's surface area. The cone size to use depends on soil hardness: the harder the soil, the smaller the cone should be — but the larger the cone, the more precise the measurement.

Applications

• Geotechnical soil research
• Trafficability or bearing-capacity research (e.g. construction sites)
• Checking artificial soil compaction
• Researching soil growing conditions for plants
• Detecting compacted layers in soil (e.g. plough sole)
