An easy to use, lightweight electronic penetrometer for storing and processing 1000 measurements of the resistance to penetration of the soil.Contact Van Walt
Using various cones connected to probing rods, the cone is pushed slowly and regularly into the soil. The depth reference plate, which is on the soil surface, reflects the signals of the ultrasonic sensor, which results in a very accurate depth measurement. The depth reference plate is also used to reflect the signals which are used to control the penetration speed. The measured resistance to penetration and the GPS coordinates are stored in the internal logger of the pentrologger.
