The penetrograph is a devise for determination of the penetration resistance of the ground. The standard set is equipped with various penetration cones, recorder pens, probe rods and recording charts. The entire set, including spare parts, instructions, cone check and the tool are packed in an aluminium carrying/transport case. Every penetrograph is supplied with a quality test report.

Applications

• General soil science examinations (e.g. for profile descriptions, obtaining data for evaluating the suitability of soils).
• Checking the suitability of soils for carrying vehicles or pedestrians.
• Checking artificially-made compactions (e.g. sand-filled trenches).
• Checking load-bearing capacity for the installation of underground tanks.
• The detection of compacted (possibly impermeable) sub-soil layers (e.g. layers compacted below ploughed depth).
• Research into poor growing conditions, including those for trees in urban streets and parks.
• Research into the connection between the intensity of rooting of specific crops and the resistance to penetration of the soil layers present.

Benefits

• Writes obtained forces with depth on chart
• Will perfectly show disturbing layers
• Will proof compaction situation
• Weather proof charts
• One-push measurement
• For contractors and agronomists
• Weather proof (stainless steel) body
