Heavy Duty Pocket Penetrometer
Standards:
ASTM D2573
Description:
It is a portable geotechnical test instrument, which is suitable for in-situ or indoor measurement of the liquid index of general cohesive soil, soft soil, compacted soil, red clay and loess and rough estimation of the bearing capacity of soil. Compared with hand identification, micro penetrometer can improve the description accuracy of the soil to be measured and reduce human error.
This series of micro penetrometer is a simple and practical testing instrument developed and produced by our company in combination with the characteristics of micro penetrometers at home and abroad. It is a convenient and practical instrument for geotechnical engineers and engineering survey technicians to carry out construction trench inspection and field description of foundation soil. It can meet the testing needs of urban and rural construction, railway, highway, bridge, hydropower, coal, metallurgy, petrochemical, marine and other departments.
