Penetrologger

The resistance to penetration is a means of determining the ground load-bearing capacity, and the ease with which roots will grow through the ground (important when agricultural, rural- and civil engineering techniques are involved). The resistance to penetration is a mechanical characteristic that, given a certain texture, depends on changing parameters such as degree of humidity, density and the strength of the connection between mineral particles. Measuring the resistance to penetration of the soil in a great number of measurements is best executed applying an electronic penetrometer together with a datalogger, allowing for immediate storage and processing of the data in the datalogger. To this purpose was developed the penetrologger: An electronic penetrometer with a built-in datalogger for storage and processing of a great number of measuring data (1500 measurements).

The penetration resistance is measured in many measurements with an electronic penetrometer with a data logger, the data is stored and analyzed in the data logger.
